Silicon nitride—the structural ceramic with the best comprehensive performance 1. Advantages of silicon nitride ceramics
There are three crystal structures in silicon nitride, which are , and phases, among which the and phases are the most common forms of silicon nitride. Because the nitrogen atoms are very firmly bonded, silicon nitride has good properties such as high strength, high hardness and high temperature resistance, and the hardness can reach HRA91~93; it has...
