How to synthesize ferrosilicon nitride!
Generally speaking, everyone is only familiar with the characteristics of the equipment, and laymen do not have a good understanding of this synthesis process. However, I have summarized the synthesis methods of ferrosilicon nitride that everyone often asks. You can take a look at the time:
There are two specific ways to synthesize ferrosilicon nitride. One is a new synthesis method of ferrosilicon nitride, which is the flash combustion synthesis method.
Although silicon nitride and ferrosilicon nitride are relatively common high-temperature raw materials on the market, most of the methods for producing ferrosilicon nitride use direct nitridation, carbon thermodynamic primary nitridation, and gas chromatography deposition. method, decomposition reaction method, etc. The new technology and process of flash combustion synthesis of ferrosilicon nitride, which will be explained below, can continuously synthesize silicon nitride and ferrosilicon nitride on a large scale and at low cost under atmospheric pressure.
During production, silica powder and ferrosilicon nitride are mixed, and continuously metered and fed into a continuous reaction kettle heated to 1200°C, and nitrogen is introduced at the same time. Silicon nitride vermicelli and ferrous silicon nitride are evenly dispersed, and due to the action of gravity and nitrogen friction resistance, they float and fall in the hot nitrogen, fully contact with the hot nitrogen to transfer heat, and are heated extremely quickly, and are burning The reaction zone and nitrogen quickly produce combustion synthesis reaction. The reaction itself generates a large amount of heat, which can self-sustain the continuous development of flash combustion synthesis.
Okay, the above is an introduction to the synthesis method of ferrosilicon nitride. For more details, please pay attention to the official website.
