Ceramic powder A heterogeneous material composite composed of metals, 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 consists mainly of Ti and Cr. It can also include other metals such as Co, Ni and Fe.

According to the type ceramic phase, Cermets are divided into oxide-based (or carbide-based), carbonitride base, boride base, graphite or diamond carbide-based.

Ceramic Powder Properties

As a high temperature material between high temperature alloys and cermic materials, ceramic powder combines both the toughness and plasticity (of metals) and the melting point, corrosion and wear resistance (of ceramics).

It is extremely resistant against high temperatures. The strength of ceramic powder can be maintained at 1200degC and above without deteriorating. 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 harsh environment and technical requirements, such as high temperatures, wear resistances, high strength and stability. 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 and oxidation resistance, make it an indispensable material in manufacturing, processing and especially for 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.
