Product Description

PCB electronic silicon nitride ceramic sheet substrate chip potsherd
Reputation depends on quality, quality comes from Hard!


Silicon Nitride Ceramic:

Silicon nitride ceramic is an inorganic material ceramic that does not shrink when sintered. Silicon nitride is very strong, especially hot pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density and high temperature resistance.
Si3N4 ceramic is a covalent bond compound. The basic structural unit is a [SiN4] tetrahedron. The silicon atom is located at the center of the tetrahedron. There are four nitrogen atoms around it, which are located at the four vertices of the tetrahedron, and then every three A tetrahedron shares the form of an atom, forming a continuous and robust network structure in three dimensions.

 

Si3N4 ceramic is an important structural material. It is a kind of super-hard material. It is lubricious and wear-resistant. It does not react with other inorganic acids except hydrofluoric acid. It has strong corrosion resistance and resistance at high temperature. Oxidation. Moreover, it can withstand cold and hot shock. It is heated to above 1,000 °C in air, and is rapidly cooled and heated rapidly without cracking. It is because of the excellent characteristics of Si3N4 ceramics that people often use it to manufacture bearings. Mechanical components such as gas turbine blades, mechanical seal rings, permanent molds, etc. If the silicon nitride ceramics with high temperature resistance and heat transfer resistance are not used to manufacture the heating surface of the engine components, the quality of the diesel engine can be improved, the fuel can be saved, and the thermal efficiency can be improved. China, the United States, Japan and other countries have developed such diesel engines.
 

Silicon Nitride 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.
