Cordierite porcelain (2MgO•2Al2O3•5SiO2) also known simply as cordierite, is a magnesium aluminum silicate produced by fusing a mixture of talc, clay and aluminum oxide. Cordierite and cordierite mineral precursors are also known as magnesium-alumino silicate, dichroite and iolite. Cordierite porcelain has a low coefficient of thermal expansion, high mechanical strength, and low dielectric loss. Cordierite is commonly fabricated into insulator or insulating substrate due to its good dielectric properties. Cordierite has excellent thermal shock resistance, withstanding red heat to ice water quench, and then returned to red heat. High fire cordierite body will withstand a temperature rise from 70º to 1800º in 80 seconds, followed by an immediate room temperature air quench. Products & Services
Industrial ceramic materials are non-metallic, inorganic compounds that include oxides, carbides, or nitrides. They have high melting points, low wear resistance, and a wide range of electrical properties.
Ceramic tube and ceramic rod products are suitable for use in applications requiring high temperature strength, erosion resistance, electrical or thermal insulation, and other specialized characteristics.
Refractory shapes include recasted, preformed or sintered refractory products that are formed prior to installation in furnaces, boilers or other high temperature equipment.
Oxide ceramics include alumina, zirconia, silica, aluminum silicate, magnesia and other metal oxide based materials.
Dielectric ceramics and substrates are electrical insulators with dielectric strength, dielectric constant and loss tangent values tailored for specific device applications.
