Ceramic powder A heterogeneous material composite composed of metal, alloys, and one or multiple ceramic phases.
Cermets are usually ceramic phases of high melting point oxides, such as Al2O3, ZrO3, beO, and MgO. ), nitrides (TiN, BN, Si3N4, etc. ), carbides (TiC, WC, etc. ), borides (TiB2, ZrB2, etc.) The metal phase can be composed mainly of Ti and Cr. It may also include Ni, Fe, Co or other metals.

Based on the type of ceramic, cermets fall into five main categories: carbide, oxide, carbonitride, boride, graphite, or diamond carbide.

Ceramic Powder Properties

Ceramic powder, a hybrid material for high temperatures, combines metals’ toughness and plasticity with ceramics’ high melting point and corrosion resistance.

It is very resistant to high heat. Ceramic powder can withstand temperatures up to 1200degC. It won’t melt when heated and will decompose at 1900degC. It has an amazing chemical resistance, and is also a high-performance electrical insulating material.

Applications for Ceramic Powder

1. Aerospace
Aerospace cermets offer a lot of potential for further development, due to the extreme environmental conditions and technical demands such as high temperatures, wear resistance and high strength. Ceramic powder can be used in the manufacture of stationary rings and valves for aerospace or aviation engines. It has excellent abrasion and high-temperature resistance.

2. Manufacturing and Processing Fields
The ceramic powder’s high hardness and wear resistance, as well as its good toughness, oxidation resistant, and other properties, make it indispensable in the manufacturing and processing industry, particularly in measuring and cutting tools.

3. Other areas
In addition to the high temperature and corrosion resistant ceramic powders used in metallurgy, the wear-resistant and high temperature resistant parts are used in machinery and electronics industries.
