Silicon Nitride

Silicon Nitride

This Silicon Nitride is an important structural ceramic material. It is a superhard substance. It has excellent thermal shock resistance and high temperature strength. It is almost as light as silicon carbide (SiC), but its microstructure gives it excellent thermal shock resistance, and its high fracture toughness makes it resistant to shock and impact. It is very versatile. It is commonly used to make mechanical parts such as bearings, gas turbine blades, mechanical seal rings and permanent molds.
