0.1-0.3% CrO Content White Calcined Kaolin Clay Clinker for Clay Bricks

white calcined kaolin flint clay clinker for clay bricks

calcined kaolin flint clay clinker, high quality hard refractory clay. The Al2O3 content in the standard calcined kaolin flint clay clinker 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.

Characteristics of calcined kaolin flint clay clinker:

1. heat resistance

calcined kaolin flint clay clinker is a mixture of various aluminosilicates. The main chemical composition is Al2O3 and SiO2 two oxides, impurities are mainly alkali, alkaline earth and iron, titanium and other oxides, and some organic matter. These oxides play the role of help melting, will reduce the refractoriness of raw materials. Therefore, the lower content of impurity in calcined kaolin flint clay clinker, especially the lower Na2O + K2O, the higher the refractoriness. And the ratio of Al2O3 / SiO2 is closer to the theoretical value (A / S = 0.85), then the higher purity of calcined kaolin flint clay clinker. Larger A / S, higher the refractoriness, and wider the sintering melting range. High quality calcined kaolin flint clay clinker refractoriness can up to 1750 ℃ or more.

2. sintering

calcined kaolin flint clay clinker has good characteristics of stable volume, strength and small water absorption after high temperature calcined. To measure the sintering degree of calcined kaolin flint clay clinker, general indicators are the true proportion, bulk density, porosity, water absorption, shrinkage and so on. Good sintered calcined kaolin flint clay clinker’s water absorption is less than 5%, bulk density is more than 2.55g / cm3.

 calcined kaolin flint clay clinker is used for the production of high-grade refractory materials, ceramics, aluminum silicate refractory fiber production and military, and so on.
