Portland cement clinker is made by heating, in a cement kiln, a mixture of raw materials to a calcining temperature of above 600 C (1,112 F) and then a fusion temperature, which is about 1,450 C (2,640 F) for modern cements, to sinter the materials into clinker.. The materials in cement clinker are alite, belite, tricalcium aluminate, and tetracalcium alumino ferrite.
