What are the applications of ferrosilicon nitride in artillery mud

What are the applications of ferrosilicon nitride in artillery mud:

1. Compared with the addition of silicon carbide or silicon nitride to the cannon mud, the high-temperature flexural strength at many temperatures has been improved to varying degrees, and ferrosilicon nitride can be decomposed to produce nitrogen at high temperature, and dispersive tiny pores are produced in the cannon mud, which is conducive to improving the drilling rate of the cannon mud;

2. The key to the application of ferrosilicon nitride different from silicon carbide and silicon nitride in artillery mud is that there are ductile particles in ferrosilicon nitride to enhance iron and intermetallic compound iron silicide, which promotes the sintering of artillery mud and improves the bonding strength between oxide and non-oxide;

3. In the clay, with the increase of ferrosilicon nitride addition, the flexural strength increases correspondingly in the temperature segment; When ferrosilicon nitride is added more than a certain amount, the porosity of the mortar increases significantly, and the flexural strength of each temperature section decreases accordingly.

4. There is almost no difference in the resistance of slag and iron erosion of the cannon mud with silicon carbide, silicon nitride and ferrosilicon nitride respectively. The addition of ferrosilicon nitride has little effect on the slag resistance and iron erosion resistance of the gun sludge.

The above are some suggestions, I hope it will be helpful to everyone!
