Silicon nitride​ is a compound synthesized under artificial conditions. Although silicon nitride was synthesized directly more than 140 years ago, it was only remembered as a stable "refractory" nitride. After the Second World War, the rapid development of science and technology, the urgent need for high temperature resistance, high hardness, high strength, corrosion resistant materials. Read More »

In recent years, material scientists have synthesized a new class of 312 ceramic materials​, whose general formula is M3XZ2, in which M is one or several transition metal elements (such as Ti, V, etc.), X is one or several main group elements, multiple III and IV main group elements (such as Al, Ge, Si, etc.), Z is one or several non-metallic elements (such as C, N, B, etc.).

Aluminum nitride​ has high resistivity, high thermal conductivity (8-10 times of Al2O3), and low expansion coefficient similar to silicon, making it an ideal material for high temperature and high power electronic devices. Commonly used ceramic substrate materials are beryllium oxide, alumina, aluminum nitride, etc., among which alumina ceramic substrate thermal conductivity is low, thermal expansion coefficient and silicon do not match; Read More »
