Refractory clay product calcined flint clay
Flint clay are a mixture of aluminum silicates.The main chemical constituents are Al2O3 and SiO2, and the impurities are mainly alkali, alkaline soil, iron, titanium and other oxides, as well as some organic compounds.All kinds of oxides play a role in melting, which can reduce the refractoriness of raw materials.Therefore, the lower the impurity content, especially the Na2O+K2O content, the higher the fire resistance.The closer the Al2O3/3SiO2 ratio is to the theoretical value (A /S=0.85), the higher the purity of the gemstone is.The larger the A/S, the higher the fire resistance of the gemstone, the wider the sintering melting range.The chamotte refractoriness with high quality can reach more than 1750 ℃.
