CC1 Sintered Ceramic Sand is a kind of sintering ceramsite sand. The raw material is inspected strictly and grinded in homogenization and then batch charged by numerical control to be granulated under great force to get accurate particle size distribution after balls sintered in the high temperature and then mixed according to grade. The CC1 Sintered Ceramic Sand is a new inorganic material mainly composed of corundum phase and supplemented by mullite and andalusite phase.
