Fused mullite ex-purity fused mullite spot wholesale, mullite powder

Mullite is a high quality refractory materials, mainly high-purity fused mullite, fused mullite general, all-natural bauxite ore sintering mullite and mullite light burning. http://www.gwncw.com Mullite is a series of aluminum silicate minerals collectively, this relatively rare minerals. Mullite is an aluminosilicate minerals produced at high temperatures, the formation of artificial heating aluminum silicate mullite. Natural mullite crystals and needles are radially elongated clusters. Mullite quarry was used to produce high temperature refractory material. Mullite is often depressed binary system Al2O3 -SiO2 the only stable binary compounds of formula 3Al2O3-2SiO2, natural mullite very small, usually by sintering or other synthetic fused law. Mullite formula: A1xSi2-xO5.5-0.5x density: 3.16g / cm3 Mohs hardness: 6 to 7 Mullite is a high quality refractory materials, mullite expansion uniform, mullite thermal shock resistance excellent mullite Takaishi load softening point, mullite high-temperature creep of small value, hardness mullite, mullite good resistance to chemical corrosion. Sintered mullite / mullite sintering of sand M70 / sintered mullite M70 / mullite Mullite is an excellent refractory raw materials, mainly sintered mullite, fused mullite.
