Refractory Calcined Flint Clay High Purity With Shell Shaped Section

Calcined China Flint Clay of Chamotte Sand Used for Materials of Refractory Industry with High Purity

1. Production Introduction and Application

Calcined Flint clay of Chamotte sand is a kind of high quality hard refractory clay produced in Zibo area, Shandong Province, China.

The Al2O3 content of the standard raw ore is 38%, the Al2O3 content after calcination is about 44%, Fe2O3 < 2%. It has stable composition, uniform texture, compact structure, shell shaped section and white color, and is used to produce high-quality clay refractories.

The technical term is first-class hard clay clinker, the main chemical composition is Al2O3 and SiO2, with a small amount of Fe2O3 and a small amount of Na2O and K2O, and the main mineral is kaolin.
