It is produced by melting mixed pure quartz sand and industrial alumina in huge electric arc funace. With the high content of mullite crystal, high melting point, excellent thermal stability, low
reversible thermal expansion and resistance to thermal shock and chemical corrosion at high temperature, the fused mullite can be widely used as lining bricksin glass body kiln and large hot wind
furnace in iron-making blast furnace, as well as in ceramic kiln and petrochemistry. Physical Properties Chemical Composition FM-70 FM-75 Al2O3 70-74% 74-77% SiO2 25-28% 22-25% Na2O 0.25%max.
