Calcined flint clay is one type of hard fire clay,which main content is Al2O3 and SiO2, Al2O3/SiO2 is about 0.85.it is one of raw materials for refracotry and ceramic.Its impurity is Na2O and K2O,it is very tiny content.Calcined flint clay has good refractoriness,which is about 1750degree, while Fe2O3 is very low ,about 1.5%.it also has low water absorption ,big density and low A.P.It is widely use for super grade refractory product, ceramic fiber products etc.Its bulk density is above 2.55g/cm3,also with stable chemical structer.
