Flint clay a high-quality hard refractory clay, the standard Al2O3 content of 38%, the Al2O3 content after calcination is about 44%, and Fe2O3<2%. The composition is stable, the texture is uniform, the structure is dense, the section is shell-like and white, and it is used for the production of high-quality clay refractories.
