Quality Calcined Flint Clay Kaolin for Refractories or Foundry Casting Investment
1. Calcined Flint Clay Introduction
Flint Clay is a kind of high quality hard refractory clay. The content of Al2O3 in the standard raw coke gem is 38%. After calcination, the content of Al2O3 is about 40-46%, and Fe2O3 is less than 3%.The composition is stable, the texture is uniform, the structure is compact, the cross section is shell-like with color white, which is used to produce the high quality clayey refractory.The technical term is first-class hard clay clinker, the main chemical composition is Al2O3 and SiO2, accompanied by a small amount of Fe2O3 and trace other chemicals.
