About Tantalum Silicide TaSi2 Powder:
Tantalum silicide TaSi2 powder is with uniform particle size, structural stability. Tantalum silicide has excellent properties such as high melting point, low resistivity, corrosion resistance, high-temperature oxidation resistance, and good compatibility with silicon, carbon and other matrix materials. Tantalum silicide TaSi2 powder is used as the gate material, integrated circuit connection line, high-temperature oxidation resistance coating, etc., Has been widely researched and applied in electric heating elements, high-temperature structural parts, electronic devices, etc.
 
Tantalum is particularly resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid. Metal silicides have similar metal conductivity, high-temperature performance, oxidation resistance and compatibility with the production process of silicon integrated circuits. Transition metal silicides can be used for low-resistance gates and interconnections, and resistance contacts.

How is Tantalum Silicide TaSi2 Powder produced?
The preparation methods of tantalum silicide include combustion synthesis (combustion synthesis, CS) or self-propagating high-temperature synthesis, arc melting, etc.
1. Using metal tantalum and silicon powder as raw materials, pulverize metal tantalum and silicon powder and mix them evenly, then put them in a graphite furnace and heat to 1100-1500°C for pre-reaction, then pass in hydrogen gas, and then heat to 800 The reaction is carried out at ℃ to obtain tantalum silicide. Or reduce tantalum pentoxide with calcium hydride to obtain tantalum hydride, and then heat to 1800°C to obtain metallic tantalum, and then add silicon powder to synthesize tantalum silicide.
2. Preheat the Si and Ta mixture to 350°C, then heat to 1480°C, and heat the reaction. Or make TaS2 react with SiHnX4-n at 900℃.
3. Direct method “Total silicide is prepared from tantalum metal and silicon powder as raw materials. The reaction formula is as follows.
First, pulverize and mix tantalum metal and silicon powder uniformly, and then put them in a graphite furnace and heat them to
Perform a pre-reaction at 1100-1500°C, then pass in hydrogen, and then heat up to 1800°C for a homogenization reaction for 1 hour to obtain tantalum silicide.
4. Tantalum pentoxide reduction method: firstly reduce tantalum pentoxide with calcium hydride to obtain tantalum hydride, then heat to 1800°C to obtain tantalum metal, and then add silicon powder to synthesize tantalum silicide.

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.

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.
