Boron nitride is a crystal composed of nitrogen atoms and boron atoms. So how much do you know about its production method? Follow the editor of Discount Boron nitride for aluminum extrusion to have a simple look!
1. Hydrothermal synthesis
This method uses water as the reaction medium in the high-temperature and high-pressure reaction environment in the autoclave to dissolve the normally insoluble or insoluble substances, and the reaction can also be recrystallized. The hydrothermal technology has two characteristics, one is its relatively low temperature, and the other is that it is carried out in a closed container to avoid the volatilization of the components. As a low-temperature and low-pressure synthesis method, it is used to synthesize cubic boron nitride at low temperatures.

2. Carbothermal synthesis technology
The method uses boric acid as a raw material on the surface of silicon carbide, carbon as a reducing agent, and ammonia nitriding to obtain boron nitride. The resulting product has high purity and has great application value for the preparation of composite materials.
3. Ion beam sputtering technology
Using particle beam sputtering deposition technology, a mixed product of cubic boron nitride and hexagonal boron nitride is obtained. Although this method has fewer impurities, it is difficult to control the reaction conditions, so the morphology of the product is difficult to control, and the research on this method has great potential for development.
The above is the editor of Discount Boron nitride for aluminum extrusion: a brief introduction to the knowledge about the production method of boron nitride.
