Silicon Nitride Ceramic:

There are basically two types: the first is a linear structure, and a polymer compound with this structure is called a linear polymer compound; the second is a body structure, and a polymer compound with this structure is called a bulk polymer Compound. Some polymers are branched, called branched polymers, which are linear structures. Although some polymers have cross-links between molecules, they are less cross-linked, which is called a network structure and belongs to a body structure. Two different structures show two opposite properties. Linear structure, heating can be melted, hardness and brittleness are small. The body structure is harder and brittle. Plastics have two types of macromolecules. Those made of linear polymers are thermoplastics, and those made of body-shaped polymers are thermosetting plastics. Due to the inability of natural degradability of plastic, it has become the number one enemy of mankind and has led to the tragedy of many animal deaths. For example, the monkeys, pelicans, dolphins and other animals in the zoo would mistakenly swallow the No. 1 plastic bottle thrown away by tourists, and finally died painfully due to indigestion; when I looked at the beautiful and pure sea, I walked closer, and it was actually full of them. All kinds of plastic garbage that could not be contained in the ocean, in the intestines of many dead seabird samples, all kinds of indigestible plastic were found.

properties:

High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
