Fused mullite is made of high purity raw materials in electric arc-furnaces. The grain is characterised by grayish colour and high chemical purity. The material is the most important component of refractory materials based on aluminium-silicate, having outstanding heat-shock and slag-corrosion resistance. The product is separated in the fraction between 0 to 8 mm, in compliance with the buyers’ demands.

Main characteristics: 
  • typical Al2O3 content: 76,00 %
  • typical SiO2 content: 23,5%
  • high chemical purity, grayish color
  • outstanding heat shock resistance, outstanding slag corrosion resistance
  • typical fractions (mm): 0-0,1, 0-0,5, 0,5-1, 0-1, 1-3, 3-5, 200F, 325F
  • particle size distribution: according to Motim's own prescriptions or to a specific requirement
Field of Application: 

Fused mullite is a basic material for refractory materials used in the steel industry at precision and continuous casting, at the charging holes of various furnaces, at making burner-frames, for lining ladles and off-takes. Additionally, fused mullite of MOTIM Electrocorundum Ltd. can also be used for the production of high purity mullite blocks for glass melting furnaces (superstructures and crowns).
