Fused Mullite
Fused Mullite is produced by melting mixed pure quartz sand and industrial alumina in huge electric arc funace.With the high content of mullite crystal,high meiting point,excellent thermal stability, low reversible theramal expansion and resistance to thermal shock and chemical conosion at high temperature, the fused millite can be widely used as lining bricksin glass boby kiln and large hot wind furnace in iron-making blast furnace,as well as in ceramic kiln and petrochemistry.
