Calcined Flint Clay - Al2o3 High Content, Variable Density, Low Fe2o3 | High Refractoriness, Stable Volume, Great Strength, Low Absorption, Uniform Texture

We are amongst one of the foremost organization engaged in supplying a wide spectrum of Calcined Flint Clay in Zibo, Shandong Sheng, China. Flint clay has very stable chemical composition and uniform texture. The fracture surface of flint clay is conchoidal. After the high-temperature calcination, the chemical composition of calcined flint clay is very stable, and the main composition is Al2O3 and SiO2, also with Fe2O3, Na2O and K2O. The sintering extent of flint clay is usually decided by the index of the bulk density, the porosity, the water absorption, and the shrinkage rate. Calcined flint clay has stable volume, great strength and low water absorption. The Calcined flint clay has outstanding refractoriness and major element is Al2O3 which has significant refractoriness, and the refractory temperature can be higher than 1750a .

Application: High grade refractory, refractory brick/firebrick, refractory castable, domestic ceramics, alumina-silicate refractory fiber product, clay crucible, precision founding sand, building materials
