POROUS CORDIERITE CERAMIC DISC
HIGH PURITY POROUS CORDIERITE CERAMIC
Made from the high purity mineral Mg2Al4Si5O18 which is also 2MgO·2Al2O3·5SiO2, a magnesium alumino-silicate.
This material is an extremely lightweight material with low thermal expansion and excellent strength, rigidity and thermal shock resistance; and has very good corrosion resistance to chemicals at high temperature, and high use temperature. It may be used for a variety of electrical, mechanical, and thermal applications
