1. Calcined Flint Clay Introduction
Calcined flint clay, high quality hard refractory clay. The Al2O3 content in the standard calcined flint clay ore is 38%, about 44% after calcined, and the Fe2O3 content is less than 2%. Stable composition, uniform texture, dense structure, section was shell-like, white, used for the production of high quality clay refractories. The term is “the first grade hard clay clinker”, with main chemical composition of AL2O3 and SiO2, accompanied by a small amount of Fe2O3 and trace Na2O, K2O, the main mineral is kaolin.
