Product Introduction
Corundum mullite brick is a high alumina refractory brick is composed of corundum and mullite as main crystal phases. Corundum mullite brick are made of high-purity or relatively pure raw materials.
Performance: high temperature strength, high temperature creep resistance, thermal shock resistance and erosion resistance. The physical and chemical properties of a typical corundum mullite brick are: Al2O3≥85%, Fe2O3 0.45%, apparent porosity 19%, normal temperature compressive strength higher than 80 MPa, load softening temperature higher than 1700℃, heating line change (1600℃, 3H) – 0.1%, thermal shock resistance (1100℃ water cooling) higher than 30 times.
