Thermal Conductivity Abrasion Resistance Cordierite high temperature Crucible
1. Detailed Product Description
The main chemical ingredient of Cordierite is 2MgO·2Al2O3·5SiO2,main material is steatite,clay,alumina,feldspar,etc. Manufactured by normal ceramic technical, can be used for loop framework, insulators of arc-resistance,element of composite materials,burnable nozzle of electrical insulators, and etc.
2. Applications
Alumina ceramics with superior strength, hardness, insulation, thermal conductivity, high temperature, oxidation
resistance, corrosion resistance, abrasion resistance, high temperature strength and other characteristics, it has
been widely used in engineering, mechanical seals, electronics, instrumentation, sensing, transport,
communications, and other occasions or areas. The content of 99.7%, 99%, 95% alumina products contains the
crucible, sockets, valves, electrodes, spools, wear board, alumina balls, electronic porcelain, textile porcelain
pieces, and other shaped pieces.
