JXDM-50
The low-porosity mullite brick is produced mainly from high-purity low-alumina mullite by high-pressure forming and high-temperature firing. It has excellent thermal shock resistance, high strength, good erosion resistance and strong corrosion resistance.
It is widely used in glass furnaces, lime kilns and the non-ferrous smelting industry, and is custom-made to customer requirements.
