Light Weight Mullit Isolierung feuerfester Ziegel

Light weightmullite insulation brick is madeof high grade and high purity refractory materials.The brickhas good chemicalstability and high refractoriness, and as such, could be used directly as fireproof layer in oxidation atmosphere. Thisbrick is mainly used for the furnace lining of metallurgical, petrochemical, carbon black and ceramic industries and so forth. We could supply light weight mullite insulation brick with both standard size andabnormal size.
