High alumina cement is produced by fusing selected raw material in Special furnace. After cooling, the clinker is ground using ball mills. The raw materials of high alumina refractory cement CA-70 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. The content of Al2O3 is usually controlled within 68% to 72%. The principal compounds of it are CA and CA2.
