This powder is white to off-white, or light yellow in color. It becomes darker as it is seen. Zinc sulfuride is stable in dry conditions, but if left in humid or moist air for long periods of time, it will oxidize to zinc oxide.
Zinc sulfide powder properties
Zinc sulfuride is an organic compound that has the chemical composition ZnS. Zinc sulfide will slowly oxidize if it is placed in moist air or is moistened. Zinc sulfide can be found in sphalerite. However, it is not soluble or soluble when mixed with water.
Zinc sulfuride becomes crystals when it is burned in H2S. The a variation is a colorless hexagonal crystal having a density 3.99g/cm3 at 1700°C. The b version is a colorless cubic crystal having a density 4.992g/cm3, which can be transformed to the a variety at 1020°C.
Zinc sulfuride is usually obtained through the action of zinc sulfide, hydrogen sulfide, and zinc salt solution. A small amount of Cu Mn, Ag can be added as an activator to the crystalline ZnS. It will emit different colors of fluorescence when illuminated.
Zinc Sulfide Powder Application
Zinc sulfuride is used for analytical reagents, phosphor matrix and photoconductor material. It is also used in dyes, paints pigments, glass and curing oil.
Zinc sulfuride is easy to dissolve and not agglomerate. It is also neutral white and has great optical properties. It is commonly used as a component in thermosetting plastics.
It is often used to make ceramics due to its good sintering qualities. Studies have shown that monodisperse Zinc Sulfide Powder has a better sintering result than agglomerate Zinc Sulfide. Furthermore, the particle size is affected and can be increased to improve the sintering performance.
Because nano-zinc sulfuride is a photonic materials, it can generate photon hole. Also, the energy level change as well as the widening energy gap caused by the quantum effect improve its redox capability. It is a photocatalytic semiconductor that excels in this role.
Zinc sulfuride is an infrared-optical material. It has high infrared transmittance, excellent optical and mechanical performance and thermal comprehensive performance within the 8-12ym and 3-5p.m bands. It is the best dual band infrared observation window available for aircraft and hoods.
