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.
