What Are The Properties Of Synthetic Cordierite

Chemical formula of cordierite2MgO·2Al2O3·5SIO2,theoretical composition MgO13.7%，Al2O3 34.9%，SIO2 51.4%,B.D 2.57-2.60g/cm3,The decomposition temperature is 1460 ℃, with a low and uniform expansion coefficient of 1.5 * 10-6 / K (20-1000 ℃)However, there are few natural cordierite ores with mining value. The cordierite used in industry are synthetic cordierite, including sintering method and electrofusion method. As a kind of refractory material, cordierite synthetic material has the most prominent characteristics of low and uniform expansion coefficient and good thermal shock stability. The raw material can be made into cordierite refractory brick, cordierite kiln furniture, cordierite filter and other products, which can be used in metallurgy, chemical industry and automobile exhaust treatment
