Take you to understand the characteristics of silicon brick refractory products
The higher the SiO2 content in the silica raw material, the higher the refractoriness of the product. Impurities such as K2O.Na2O are harmful and will seriously reduce the refractoriness of refractory products. Fe2O3, CaO, MgO and other impurities play the role of flux. The raw materials of high-grade silicon bricks need special treatment to remove impurities.
The mineral composition of the silicon brick is a complex structure of squamous quartz, cristobalite, a small amount of residual quartz and glass formed at high temperature. The mineral composition fluctuates greatly according to the different production process of silicon brick and the properties of raw materials used.
