Description
Rongsheng Mullite Bricks Description
Mullite bricks are high alumina refractories with mullite as the main crystal phase. Generally, the alumina content is between 65% and 75%, and the refractory of mullite brick is relatively high, reaching above 1790 ℃. The starting temperature of load softening is 1600 ~ 1700 ℃. Good thermal shock resistance. There are two kinds of sintered mullite bricks and fused mullite bricks.Standard size 230 x 114 x 65 mm or according to customer requirements.
