About Calcium Nitride Ca3N2 powder
In most cases, calcium nitride is usually available in large volumes. Tqhp 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.

About Zinc Telluride ZnTe Powder:
Zinc Telluride is a Group II-VI compound with the chemical formula ZnTe. In a hydrogen atmosphere, tellurium and zinc are heated together and then sublimated to produce reddish-brown zinc telluride. Because zinc telluride has a wide bandgap, it is often used to make semiconductor materials. Zinc Telluride is a semiconductor material with a direct bandgap of 2.26 eV. Usually a p-type semiconductor.
Zinc telluride usually has a cubic (galena or “zinc blende”) crystal structure, but it can also be prepared as rock salt crystals or hexagonal crystals (wurtzite structure). Under aerobic conditions, it will burn when irradiated by a strong beam. After refined by sublimation, the appearance of ZnTe is a gray or brownish-red powder or ruby red crystals. ZnTe has a lattice constant of 0.6101 nm and can be grown with or on aluminum antimonide, gallium antimonide, indium arsenide, and lead selenide. Due to certain lattice mismatches, ZnTe can also be grown on other substrates (such as GaAs) and can be grown on substrates such as glass in the form of thin-film polycrystalline (or nanocrystalline) on substrates such as glass. Thin-film solar cells. In the wurtzite (hexagonal) crystal structure, its lattice parameters a = 0.427 and c = 0.699 nm.

Performance of Telluride copper CuTe powder:
Copper telluride is a chemical substance with the molecular formula CuTe. Copper telluride is a black powder, which is relatively stable in air at room temperature. Copper telluride is not only an important inorganic material but also an excellent form of storing tellurium and copper resources. In the H2SO4 solution, replacing Te with Cu generates copper telluride, which separates tellurium from many metal ions and obtains a relatively high concentration. When Cu replaces Te, Te can be + 4 valences or + 6 valences, all of which can generate Cu 2 Te, that is, it is not affected by the valence state of tellurium. In the presence of an oxidizing agent, copper telluride can chemically react with acids or bases, which is also the basis for separating and recovering Cu and Te. In short, tellurium and copper combine with each other at a higher temperature to recover tellurium from the solution.
Specification of Telluride copper CuTe powder :
Black crystal powder, room temperature is stable in the air. Copper telluride is not only an important inorganic material, or stores a great form of tellurium and copper resources.
