Mullite bricks are a kind of high alumina refractory with mullite (3Al2O3 2SiO2)
as the main crystalline phase and contain 65 ~ 75% alumina content
High fire resistance, up to 1790 ℃ above. The initial softening temperature of the load is 1600 ~ 1700 ℃. Compressive strength at normal temperature 70 ~ 260MPa. Good thermal shock resistance
Three types of high alumina refractories
- Low mullite and mullite base (w (Al2O3) = 48% ~ 71.8%)
- Based on mullite-corundum and corundum-mullite (w (Al2O3) = 71.8% ~ 95%)
- Corundum based (Al2O3 ＞ 90%)
