Silica brick is a refractory product containing SiO2 as a main component. Its SiO2 content is generally not less than 93%. Silica brick is an acidic refractory material. It has strong resistance to acid slag and good resistance to oxides such as CaO, FeO and Fe2O3. However, it has poor resistance to alkaline slag erosion and is easily oxidized by Al2O3, K2O and Na2O. Destruction by the action of matter. The softening temperature of the silicon brick load is as high as 1640~1680�°C, and the long-term use volume is stable under high temperature. However, silica bricks have poor thermal shock resistance and high refractoriness. When using silica bricks, pay attention to two points: when the silica brick is at 200~300�°C and 573�°C, the volume suddenly expands due to the crystal transformation. Therefore, the temperature rise below 600 �°C in the oven should not be too fast, when it is cooled to below 600 �°C. Dramatic temperature changes should be avoided; as far as possible not in contact with the alkaline slag. Application Coke oven, Hot blast stoves, Crown or Superstructure of glass furnace.
