Calcium Nitride Ca3N2 Powder CAS 12013-82-0

About Calcium Nitride Ca3N2 powder
In most cases, calcium nitride is usually available in large volumes. Orachemicals provides a wide range of products for hydrogen storage research, advanced fuel cells, and battery applications. Hydrogen is easily produced from renewable energy sources and is the most abundant element in the universe. Hydrogen comes from many sources, such as solid fuels, water, and renewable materials. Hydrogen is non-polluting and will form harmless water during use. Challenges related to the use of hydrogen as an energy source include the development of safe, compact, reliable, and cost-effective hydrogen storage and transmission technology. Currently, hydrogen can be stored in three forms: compressed hydrogen, liquid hydrogen, and chemical storage. High purity, submicron and Nanopowder forms can be considered. Calcium nitride is the main raw material for high-end phosphors. This phosphor is more stable, has better performance, and has better effects at high temperature and high humidity. Last but not least, calcium nitride can also be used as a chemical treatment agent, which is the key to determining the performance of water-based mud. Feel free to send an inquiry to get the latest price if you would like to buy Calcium nitride in bulk.
How is Calcium Nitride Produced?
When calcium burns in the air, it forms Ca3N2 with the oxide CaO. The distilled fibrous metallic calcium is heated to 450°C in a purified nitrogen stream, and then the metallic calcium is nitrided into calcium nitride after 3-4 hours.
Depending on the preparation temperature, the obtained calcium nitride is black at 350°C, milky white at 350 to 1150°C, or golden yellow at 1150°C or higher. It is easy to identify the calcium nitride formed because it can react with moisture or water and produce calcium hydroxide and ammonia.
Applications of Calcium Nitride
Ca3N2 can be used for obtaining reactive nitride ions, Calcium hydride (a desiccant) can be produced by heating calcium nitride with hydrogen at temperatures above 350 °C.

Molybdenum Silicide MoSi2 Powder CAS 12136-78-6

 About Molybdenum Silicide MoSi2 Powder: 
MoSi2 is an intermetallic compound, molybdenum silicide is a refractory ceramic, mainly used for heating elements. It has a medium-density, a melting point of 2030 ° C, which is electrically conductive. At high temperatures, it forms a passivation layer of silica to protect it from further oxidation. The thermal stability of MoSi2 and the thermal stability of its high radiation make such materials and high radiation coatings in thermal shields from the atmosphere as they are used next to WSI2. MoSi2 is a material with a four-square crystal structure (α-modified) gray metal; its β-modification is hexagonal and unstable. It is insoluble in most acids but is dissolved in nitric acid and hydrofluoric acid.
 
Although molybdenum silicide has excellent oxidation and high Young's modulus at temperatures above 1000 ° C, it is brittle at lower temperatures. Moreover, at 1200 ° C or more, it will lose creep resistance. These properties are limited to their structural materials but can be shifted by using it as a composite with another material. 

Molybdenum disilicide (MoSi2) is a promising candidate material for high-temperature structural applications. It is a high melting point (2030 C) material with excellent oxidation resistance and a moderate density (6.24 g/cm3). However, low toughness at low temperatures and high creep rates at elevated temperatures have hindered its commercialization in structural applications. Much effort has been invested in MoSi2 composites as alternatives to pure molybdenum disilicide for oxidizing and aggressive environments. 

Molybdenum disilicide-based heating elements have been used extensively in high-temperature furnaces. The low electrical resistance of silicides in combination with high thermal stability, electron-migration resistance, and excellent diffusion-barrier characteristics is important for microelectronic applications. Feel free to send an inquiry to get the latest price if you would like to buy Molybdenum Silicide MoSi2 Powder in bulk.

Characteristics of Molybdenum Silicide MoSi2 Powder:
Molybdenum silicide MoSi2 powder (CAS 12136-78-6) has high melting point, high corrosion resistance, high oxidation resistance, good electrical conductivity, high temperature ductility, a binary alloy system the intermediate phase, dual characteristics of metals and ceramics.

>99%>60%balance0.2%0.02%0.19%0.015%0.05%


How is Molybdenum Silicide MoSi2 Powder produced?
Molybdenum disilicide and MoSi2-based materials are usually made by sintering. Plasma spraying can be used to produce dense monoliths and composite forms. The material produced by this method may contain a certain proportion of β-MoSi2 due to its rapid cooling.

Applications of Molybdenum Silicide MoSi2 Powder:
Molybdenum disilicide heating elements can be used for temperatures up to 1800 ° C, in electric furnaces used in laboratory and production environment in the production of glass, steel, electronics, ceramics, and in heat treatment of materials. Molybdenum disilicide is used in microelectronics as A Contact Material.

Heating element
MoSi2 is a conductive silicide that has an oxidation property due to a stable silica layer on its surface at a high temperature.
Although the top MoSi2 element can operate at temperatures up to 1800 ° C, the material is very brittle, which may suffer serious creep during use. However, they have process advantages because they can work under high electrical loads without aging, and will not exhibit increased resistivity during use. They have antioxidant properties in air, oxygen and oxygen-rich atmosphere.
Moreover, they can be used with ammonia, nitrogen, hydrogen, a rare gas, and limited vacuum, but due to the failure of the protective oxide layer, the operating temperature and life can be reduced.

MoSi2 elements are ready-made elements and can be made into a bending or straight form of a variety of sizes. These elements are mainly used in production furnaces and laboratory furnaces in ceramics, glass, steel, electronics and heat treatment industries.

High-temperature structure
Amazingness and high-temperature elasticity make MoSi2 a very promising material for high-temperature applications such as gas turbine engines. Many researchers strive to improve high temperature creep resistance and low-temperature ductility. However, there are no commercially available composites with all preferred features.
