High-grade refractory and ceramic products
Calcium nitride has the characteristics of a high melting point, high hardness, excellent chemical stability, and high-temperature thermal stability, so it is widely used as a raw material for high-grade refractory materials and ceramic products. Calcium nitride can be used in the manufacture of high-grade refractory bricks, high-temperature stoves, high-temperature furnace tubes, ceramic cutting tools, etc. In terms of ceramic products, calcium nitride can be used to manufacture high-strength and high-hardness ceramic products, such as advanced ceramic tableware, advanced ceramic cutting tools, etc.
Second, the metal surface treatment agent
Calcium nitride can be used for metal surface treatment to improve the hardness and wear resistance of metal surfaces. When calcium nitride is used as a surface treatment agent, it can react with the metal surface through thermal diffusion or chemical reaction to form a dense nitride layer. This treatment method is especially suitable for mechanical parts with high strength and high wear resistance, such as automobile engine parts and hydraulic system parts.
Third, raw materials of metal nitriding furnace
A nitriding furnace is an equipment used for metal nitriding treatment; calcium nitride can be used as one of the raw materials of metal nitriding furnaces. In the metal nitriding process, calcium nitride reacts with ammonia to form nitrogen and hydrogen, and the resulting nitrogen can be used to nitride metals. In addition, calcium nitride can also react with other metal elements to produce metal nitrides, such as titanium nitride, aluminum nitride, and so on.
Manufacture high-purity nitrogen
Calcium nitride can be used to make high-purity nitrogen gas. Under certain conditions, calcium nitride reacts with ammonia to produce nitrogen and hydrogen. Through controlling reaction conditions and separation and purification, high-purity nitrogen can be obtained.

Production Method of Calcium Nitride Ca3N2 powder:
Calcium reacts with nitrogen.
The reaction of calcium with nitrogen is a common method to prepare calcium nitride. The reaction needs to be carried out at high temperatures and is generally prepared by an electric arc furnace or induction furnace. The specific steps are as follows:
The higher-purity calcium block is placed in an electric arc furnace or induction furnace and heated until it melts.
Through high-purity nitrogen, calcium reacts with nitrogen to form calcium nitride.
Adjust the nitrogen flow rate and temperature, control the reaction speed, and prevent calcium from reacting too much with nitrogen to produce calcium nitride and hydrogen.
After the reaction, the product is taken out, cooled, and crushed to obtain calcium nitride products.
The advantages of this method are that the prepared calcium nitride has high purity and fine particle size, which is suitable for the field with high purity and particle size requirements. However, this method requires the use of high-purity calcium and nitrogen, the production cost is high, and the need to use high-temperature equipment, the equipment requirements are high.
Calcium oxide reacts with nitrogen.
The reaction of calcium oxide with nitrogen is also a common method for preparing calcium nitride. The reaction needs to be carried out at high temperatures and is generally prepared in a high-temperature furnace. The specific steps are as follows:
The higher-purity calcium oxide is placed in a high-temperature furnace and heated until it melts.
Through high-purity nitrogen, calcium oxide reacts with nitrogen to form calcium nitride.
Adjust the nitrogen flow rate and temperature, control the reaction speed, and prevent calcium oxide from reacting too much with nitrogen to produce calcium nitride and hydrogen.
After the reaction, the product is taken out, cooled, and crushed to obtain calcium nitride products.
The advantages of this method are that the prepared calcium nitride has a high-purity fine particle size, calcium oxide is cheaper than calcium, and the cost is lower. However, this method requires the use of high-temperature equipment, higher requirements for equipment, and the reaction speed is slow.
Ammonia decomposition
Ammonia decomposition is a common method for preparing calcium nitride. The method is to decompose ammonia, get nitrogen and hydrogen, and then nitrogen into calcium carbide so that calcium carbide and nitrogen reaction to calcium nitride. The specific steps are as follows:
Calcium carbide is placed in the reactor and heated to a certain temperature.
Ammonia breaks down into nitrogen and hydrogen.
Nitrogen is passed into calcium carbide, and calcium carbide reacts with nitrogen to form calcium nitride.
Adjust the nitrogen flow rate and temperature, control the reaction speed, and prevent calcium carbide from reacting too much with nitrogen to produce calcium nitride and hydrogen.
After the reaction, the product is taken out, cooled, and crushed to obtain calcium nitride products.
The advantages of this method are that the calcium nitride prepared has high purity, fine particle size, and low requirement on equipment. However, this method requires the use of ammonia as a raw material, the cost is high, and the ammonia decomposition process will produce hydrogen and other flammable and explosive gases, need to pay attention to safety issues.
