Silicon Nitride Ceramic:

The original ceramic is a generic term for pottery and porcelain. That is, a molded sintered body obtained by molding and high-temperature sintering. Traditional ceramic materials mainly refer to aluminosilicates. At the beginning, people did not have high requirements for the selection of aluminosilicate, the purity was not large, the particle size was not uniform, and the molding pressure was not high. The ceramics obtained at this time are called traditional ceramics. Later, it developed to have high purity, small particle size and uniformity, and high molding pressure. The sintered body obtained by sintering is called fine ceramics. In the next stage, people researched the basis of ceramic materials that constitute ceramics, which greatly changed the concept of ceramics. The internal mechanical properties of ceramics are related to the chemical bond structure of the materials that make up the ceramics. Chemical substances that can form a relatively strong three-dimensional network structure when forming crystals can be used as ceramic materials. This mainly includes ionic compounds with relatively strong ionic bonds, simple substances and compounds that can form atomic crystals, and substances that form metal crystals. They can all be used as ceramic materials. Secondly, people have developed fiber-reinforced composite materials based on the characteristics of three-dimensional bonding. Further broaden the scope of ceramic materials. Therefore, ceramic materials have developed into a general term for materials that can be bonded in three dimensions.
