Production Method of Aluminum Nitride powder AlN powder：

Pyrolysis method

Pyrolysis is the most common method for producing aluminum nitride. The method is to generate aluminum nitride powder by pyrolysis of aluminum salt and nitride at high temperatures. The specific steps are as follows:

Aluminum salts are mixed with nitrides such as ammonia water to form a solution of aluminum salts and nitrides.

The solution is evaporated and dried to obtain a solid mixture.

The solid mixture is pyrolyzed at high temperatures to produce aluminum nitride powder.

The pyrolysis method has the advantages of a simple process, convenient operation, and low cost, so it is widely used. However, the pyrolysis method also has some shortcomings, such as the production process will produce nitrogen and other harmful gases and need to take corresponding environmental protection measures.

The second reaction method

The reaction method is to react nitrogen and aluminum powder at high temperatures to produce aluminum nitride powder. The specific steps are as follows:

Aluminum powder is placed in a vacuum reactor.

The reactor is heated to a high temperature, and nitrogen is injected to react with aluminum powder.

After the reaction is complete, the reactor is cooled to obtain aluminum nitride powder.

The advantage of the reaction method is that no harmful gases are produced in the production process, and the environmental protection performance is good. However, the disadvantage of the reaction method is that the production cost is high, and the use of high-purity nitrogen and aluminum powder is not suitable for large-scale production.

Vapor deposition method

The vapor deposition method is to produce aluminum nitride powder by reaction under the condition of gas phase. The specific steps are as follows:

Heating aluminum-containing metals or their compounds to high temperatures causes them to evaporate into a gaseous state.

Nitrogen gas is passed into the vapor of a metal or its compound at high temperatures to react with nitrogen gas.

After the reaction is complete, the reactor is cooled to obtain aluminum nitride powder.

The advantage of vapor deposition is that high-purity aluminum nitride powder can be prepared, and no harmful gases. However, the disadvantage of vapor deposition is the high cost of equipment and the need to use high-purity metals or their compounds, so it is not suitable for large-scale production.
