Aluminium Nitride Ceramic Heating Plate

 

Advantages of Aluminium Nitride Ceramic Heating Plate:

 

Aluminium nitride ceramic heating plate, with high thermal conductivity and electrical insulation properties, are an advanced ceramic material. They are widely used in the electronics industry, particularly in the form of aluminium nitride ceramic heating plates, making them an excellent choice when they are required for efficient applications.

Aluminium nitride crystal belongs to the hexagonal crystal system, which uses tetrahedron as the structural unit covalent bonding compound.At the same time, it is also a high-temperature resistant ceramic material. In applications,its single crystal thermal conductivity is about 5 times that of alumina,it can be used in the environment of 2200 °C, with good thermal shock resistance.

 

At the same time, aluminium nitride is resistant to metal erosion in the molten state. It is almost not stabilized by acid. Because the surface of aluminium nitride is exposed to moist air, it reacts to form a very thin oxide film.

The chemical formula of aluminium nitride is AlN. The chemical composition AI accounts for about 65.81%, and N accounts for about 34.19%. Its powder is generally white or gray-white. It is colorless and transparent in the single crystal state, and in the context of ceramic heating plates, the sublimation decomposition temperature under normal pressure reaches 2450 °C. This makes aluminium nitride ceramic heating plates crucial for certain high-temperature applications.

Aluminium nitride ceramics as a hard and brittle material. Sintered aluminium nitride ceramics processing is very difficult. Its various properties are superior to other ceramic materials. This also means that its processing difficulty is higher than other ceramics. Furthermore, aluminium nitride ceramic processing also has a difficulty.
