Stannic Sulfide SnS2 Powder CAS 1314-95-0

About Stannic Sulfide SnS2 Powder:
The tin disulfide is an inorganic compound with a chemical formula of SnS2. It is a yellow hexagonal flake with a CdI2 crystal structure. It is hardly soluble in water, but it is soluble in aqua regia and hot alkali solution, and also soluble in sodium sulfide solution. It is commonly used to Make golden paint.
Tin(IV) sulfide crystallizes in the form of cadmium iodide precursor crystals, where Sn(IV) is located in an "octahedral pore" defined by six sulfide centers. It naturally appears as rare mineral montmorillonite, which can be used as a semiconductor material with a bandgap of 2.2 eV.
SnS2 is an n-type semiconductor material with a hexagonal CdI2 structure. Tin disulfide (SnS2) is a layered metal dihalide semiconductor with a chemical and crystal structure similar to molybdenum disulfide (MoS2). In each individual layer, Sn is sandwiched between two Slayers with strong covalent bonds, while a single monolayer is maintained by weak van der Waals forces. When the weak van der Waals force is overcome by physical or chemical peeling, each layer will break freely.
Like many other two-dimensional semiconductors, SnS2 exfoliates to form atomic layer sheets, which can be used in FET, photovoltaic solar cells, sensors, and photocatalyst applications.
The tin disulfide is an acidic sulfide, soluble in aqua regia and hot alkali solution, and can undergo coordination reaction with concentrated hydrochloric acid, but it is insoluble in dilute hydrochloric acid, insoluble in water and nitric acid. It can react with ammonium sulfide to dissolve. Feel free to send an inquiry to get the latest price if you would like to buy Stannic Sulfide SnS2 Powder in bulk.

How is Titanium Sulfide TiS2 Powder produced?
Titanium disulfide is prepared by the reaction of the elements around 500 °C.
Ti + 2 S → TiS2
It can be more easily synthesized from titanium tetrachloride, but this product is typically less pure than that obtained from the elements.
TiCl4 + 2 H2S → TiS2 + 4 HCl
This route has been applied to the formation of TiS2 films by chemical vapor deposition. Thiols and organic disulfides can be employed in place of hydrogen sulfide.
A variety of other titanium sulfides are known.
 
Applications of Titanium Sulfide TiS2 Powder:
The prospect of titanium disulfide as a cathode material for rechargeable batteries was proposed in 1973. Groups IV and V halogen compounds have attracted attention for their high electrical conductivity. The original described battery used a lithium anode and a titanium disulfide cathode. The energy density of the battery is high, the diffusion process of lithium ions to titanium disulfide cathode is reversible, and the battery can be charged.
Titanium disulfide was chosen because it is the lightest and cheapest chalcogenide.
Lithium-ion diffuses fastest in titanium disulfide.
The main problem is the degradation of the cathode after repeated use. This reversible insertion process allows the battery to charge. In addition, titanium disulfide is the lightest and cheapest of all the IV and V groups of layered dihalides.
In the 1990s, titanium disulfide was replaced by other cathode materials (manganese oxide and cobalt oxide) in most rechargeable batteries.
The use of TiS2 cathodes in solid-state lithium batteries most lithium-ion batteries use liquid electrolytes, which can pose safety concerns due to their flammability. A number of different solid electrolytes have been proposed to replace these hazardous liquid electrolytes.
For most solid-state batteries, high inter interface resistance reduces the reversibility of the intercalation process and shortens the service life. For TIS2, these undesirable interface effects are less of a problem. The power density of the all-solid-state lithium battery is 1000 W/kg and the maximum power density is 1500 W/kg in 50 cycles. In addition, the battery's average capacity dropped by less than 10% in 50 cycles. Although titanium disulfide has high conductivity, high energy density and high power, its discharge voltage is relatively low compared to other lithium batteries with high reduction potential cathode.

Storage Condition of Titanium Sulfide TiS2 Powder:
The damp reunion will affect TiS2 powder dispersion performance and using effects, therefore, Titanium Sulfide TiS2 Powder should be sealed in vacuum packing and stored in cool and dry room, the Titanium Sulfide TiS2 Powder can not be exposure to air.

Cadmium Sulfide CdS Powder CAS 1306-23-6

About Cadmium Sulfide CdS Powder :
Cadmium sulfide is an inorganic substance with a chemical formula of CdS. There are two crystals, the α-form is a lemon yellow powder, and the β-form is an orange-red powder. Slightly soluble in water, soluble in acid, slightly soluble in ammonia. Cadmium sulfide is a yellow solid. It has two different crystal structures in nature, namely, the rare minerals clinopyroxene and leucite, but it is more commonly used as an impurity substituent in zinc ore with similar structure, sphalerite and wurtzite, while zinc ore Sphalerite and wurtzite are the main economic sources of cadmium. As a compound that is easy to separate and purify, it is the main source of cadmium in all commercial applications. Its bright yellow color made it used as a pigment for the yellow paint "Cadmium Yellow" in the 18th century.
 
Like zinc sulfide, cadmium sulfide has two crystal forms. More stable hexagonal wurtzite structure (present in Greenockite mineral) and cubic zinc mixed structure (present in Hawleyite mineral). In both forms, cadmium and sulfur atoms have four coordinates. There is also a high-pressure form with a NaCl rock salt structure.
 
Cadmium sulfide is a direct bandgap semiconductor (energy gap 2.42 eV). The proximity of its bandgap to the wavelength of visible light gives it a colorful appearance.
Both polymorphs are piezoelectric, and the hexagon is also pyroelectric.
CdS crystal can be used as the gain medium of solid-state lasers.
CdS can be used in combination with other layers in the form of thin films for certain types of solar cells. CdS is also one of the first semiconductor materials used in thin-film transistors (TFT).
 
The CdS film can be a piezoelectric film and has been used as a transducer that can operate at frequencies in the GHz range. Feel free to send an inquiry to get the latest price if you would like to buy Cadmium Sulfide CdS Powder in bulk.

How is Cadmium Sulfide CdS Powder produced?
Cadmium sulfide can be prepared by precipitation from soluble cadmium(II) salts with sulfide ions. This reaction has been used for gravimetric analysis and qualitative inorganic analysis.
 
Industrial cadmium ore is leached into cadmium sulfate with sulfuric acid, adjusted to pH=3.5 and precipitated with sodium sulfide, and the pH should not be too low.
 
The production of pigments usually involves precipitation of CdS, washing of solid precipitates to remove soluble cadmium salts, then calcination (roasting) to convert them into hexagons, and then grinding to produce powders. When cadmium sulfide selenide is required, CdSe and CdS will co-precipitate, and cadmium selenide will be generated during the calcination step.
 
Applications of Cadmium Sulfide CdS Powder :
Cadmium sulfide is called cadmium yellow and is used to color enamel, glass, ceramics, plastics and paint.
Nickel yellow is suitable for coloring almost all resins and is translucent in plastics. There is a light-colored cadmium yellow containing zinc sulfide in polyethylene, and the molding processing time should be extended appropriately because zinc sulfide will promote the decomposition of polyethylene plastic and make it green. Cadmium yellow should not be mixed with pigments containing copper or copper salts to avoid the formation of black copper sulfide or green copper sulfate. Cadmium yellow and blue pigments can be mixed together to obtain green.
Cadmium sulfide is mainly used as a pigment owing to its good thermal stability, light and weather fastness, chemical resistance, and high opacity.
Other applications of cadmium sulfide are listed below:
Photoresistors
Thin-film transistors
Transducers
Solar cells
Electrochemical deposition
Sol-gel techniques
Screen printing.

Zinc sulfide is usually made from waste materials for other purposes. Typical sources include smelters, slag, and pickling liquor. It is also a by-product of ammonia synthesis from methane, where zinc oxide is used to remove hydrogen sulfide impurities in natural gas.
 

What is zinc sulfide used for? 
The most common use of ZnS is used as a pigment for paints, plastics, and rubber. Lithopone, a mixture of ZnS and barium sulfate (BaSO4), is a widely used pigment for low-gloss paints. ZnS is phosphorescent, which makes it useful for several electronic and decorative applications.
High-purity crystal zinc sulfide powder is an important basic material widely used in high-tech fields such as civil, military, aerospace, and other high-tech fields. It is also an extremely important window material for medium-long-wave far-infrared precision guidance and far-infrared imaging, especially in national defense. Military and other cutting-edge technology fields. The applications of Zinc Sulfide are as following:
Luminescent material
Zinc sulfide, coupled with a small amount of suitable activator, has strong phosphorescence and is currently used in various applications from cathode ray tubes to X-ray screens to emit light in dark products. When silver is used as the activator, the resulting color is bright blue with a maximum of 450 nm. The use of manganese produces an orange-red color of about 590 nm. Copper can glow for a long time and has the familiar dark green glow effect. Copper-doped zinc sulfide ("ZnS + Cu") is also used in electroluminescent panels. It also exhibits phosphorescence due to impurities under blue or ultraviolet light irradiation.
Optical materials
Zinc sulfide is also used as an infrared optical material, transmitting from visible light wavelengths to just over 12 microns. It can be used as a flat surface as an optical window or shaped as a lens. It is made of hydrogen sulfide gas and zinc vapor to make microchips and sold as FLIR grade (front looking infrared), in which zinc sulfide is in creamy yellow, opaque form. When hot isostatic pressing (HIPed), the material can be converted into a transparent form of water, called Cleartran (trademark). Early commercial forms were sold as Iran-2, but this name is now obsolete.
Pigment
Zinc sulfide is a common pigment, sometimes called statolith. When combined with barium sulfate, zinc sulfide forms lithopone.
Catalyst
The fine ZnS powder is an effective photocatalyst, generating hydrogen from water when illuminated. Sulfur vacancies can be introduced into ZnS during the synthesis process. This gradually turns white to yellow ZnS into a brown powder and enhances photocatalytic activity through enhanced light absorption.

Feature of Zinc Sulfide ZnS Powder:
Zinc sulfide CAS 1314-98-3 is white to off-white or light yellow powder. See the light color becomes darker. Stable in dry air, gradually oxidized to zinc sulfate when placed in moist air for a long time or containing moisture. Soluble in dilute mineral acid, soluble in alkali, insoluble in water. The relative density is 3.98 (α-type), (d25) 4.102 (β-type). Irritating.
