Product Description

Product Description

The raw materials are high purity calcium materials and high pure alumina. The raw materials should be mixed according to suitable ratio. The raw material should be burned to partly fuse. After cooling, α-Al2O3 powder added into clinker, then ground to cement. The content of Al2O3 is usually controlled within 68% to 72%. The principal compounds of it are CA and CA2.
