EL - 70 GUN, E e NCalcium Aluminate Cement
Chemical Analysis by XRF (%)
EL - 70 is calcium aluminate cement obtained from fusion of high purity bauxite and calcium carbonate inelectric arc furnaces. It is ball milled with alumina addition which makes EL - 70 an ideal product for special refractory.
