Sinter Mullite Products

Description

Sinter mullite products are high aluminum refractory system with mullite (Al 2O3•SiO2) as the main crystal phase. Generally, the alumina content is between 65% ~ 75%. have properties of good thermal shock resistance, high strength at high-temperatures and high density. they are the first selected super materials for glass furnaces, heating furnaces, chemical kilns and metallurgic furnaces.
