Introduction of High Temperature Refractory Cement

High temperature refractory cement, also known as high alumina cement or aluminous cement, is a specialized type of hydraulic cement. It is made of natural bauxite or industrial alumina and calcium carbonate (limestone) in a certain proportion. Besides, high temperature refractory cement is obtained by heating a mixture of limestone (calcium carbonate) and bauxite (aluminum ore) in a kiln to high temperatures about 1500℃(2732℉). The resulting clinker is finely ground to produce high temperature refractory cement. In addition, it is also made by melting bauxite and limestone.
