Conventional synthesis methods of ferrosilicon nitride!
There are two main methods for synthesizing ferrosilicon nitride, a new method for synthesizing ferrosilicon nitride, namely the flash combustion synthesis method.
Although silicon nitride and ferrosilicon nitride should be a widely used high-temperature material in the market, the preparation methods of ferrosilicon nitride mostly adopt direct nitridation, carbon thermal nitridation, vapor deposition, thermal decomposition, etc. The new process of synthesizing ferrosilicon nitride by flash combustion can continuously synthesize silicon nitride and ferrosilicon nitride in large scale and at low cost under normal pressure.
During the production process, ferrosilicon fine powder is mixed with ferrosilicon nitride and continuously measured into a continuous reactor preheated to 1200℃, and nitrogen is introduced at the same time. Silicon nitride powder and silicon nitride powder are evenly dispersed, float and fall in hot nitrogen, fully contact with hot nitrogen, and quickly react with nitrogen in the combustion reaction zone. The reaction itself generates a lot of heat, and flash combustion synthesis can be carried out continuously.
Well, the above is an introduction to the synthesis method of ferrosilicon nitride. For more details, please pay attention to the official website.
