The refractory cement has passed the ISO certified, can resist a high temperature while keeping high strength. They are made from pure Al2O3 powder. It&#**9;s refractoriness will increase with the raising of CA. It is suitable to make refractory concrete as a binder and top-class refractory castable. They are widely used in metallurgy, construction, chemical and thermal power industries.
