Silicon nitride is very strong, especially hot pressed silicon nitride, which is one of the hardest substances in the world. It is extremely resistant to high temperatures, its strength can be maintained to a high temperature of 1200 °C without falling, it will not melt into a melt after heating, it will decompose until 1900 °C, and it has amazing chemical resistance and can withstand almost all inorganic acids. And less than 30% caustic soda solution can also resist the corrosion of many organic acids; at the same time it is a high-performance electrical insulation material.
