Common high temperature resistant industrial ceramics

Common high temperature resistant industrial ceramics

High temperature resistant industrial ceramics refers to ceramics with high temperature resistance for industrial production and industrial products. Now Pintejin Zirconia Ceramics Factory will tell you the common high temperature resistant industrial ceramics.

High temperature-resistant industrial ceramics are a type of fine ceramics, which can play mechanical, thermal, chemical and other functions in applications. Because industrial ceramics have a series of advantages such as high temperature resistance, corrosion resistance, wear resistance and erosion resistance, they can replace metal materials and organic polymer materials in harsh working environments.

99 alumina high temperature industrial ceramic flange

Alumina Ceramics:

The ceramic is a ceramic with AL2O3 as the main component (the mass fraction of AL2O3 is >45%). According to the difference of the main crystal phase in the porcelain blank, it can be divided into corundum porcelain, corundum-mullite porcelain and mullite porcelain, etc.; It can be divided into 75 porcelain, 95 porcelain and 99 porcelain according to the mass fraction of AL2O3.


Alumina high temperature industrial ceramics have high melting point, high hardness, high strength, and have good chemical corrosion resistance and dielectric properties. However, it is brittle, has poor impact resistance and thermal shock resistance, and cannot withstand drastic changes in ambient temperature. It can be used to manufacture furnace tubes, furnace linings, and spark plugs of internal combustion engines for high-temperature furnaces. It can also be used to manufacture high-hardness cutting tools.

Silicon carbide high temperature industrial ceramics

Silicon carbide ceramics:

The biggest feature of silicon carbide high temperature resistant industrial ceramics is high high temperature strength, high thermal conductivity, high wear resistance, corrosion resistance and creep resistance. It is used to manufacture high temperature parts such as nozzle of rocket tail nozzle, throat for pouring metal, thermowell, furnace tube and so on.


Due to its high thermal conductivity, it can also be used to manufacture high-temperature strength parts such as blades and bearings of gas turbines, as well as materials for high-temperature heat exchangers and encapsulation materials for nuclear fuel.
