Lightweight silica bricks, the main component of lightweight silica bricks is silicon dioxide (SiO₂). Its manufacturing process usually involves mixing silicon ore or high-purity silica sand with a binder and firing it at high temperature. have the characteristics of low thermal conductivity, good volume stability, high refractoriness under load, and high working temperature.
Performance of Lightweight silica bricks：
Lightweight silica bricks are widely used in various high-temperature industrial equipment due to their high-temperature stability and excellent insulation properties, providing an effective solution for energy saving and improving production efficiency.
1. Refractory: Lightweight silica bricks can maintain stability at high temperatures and can usually withstand temperatures exceeding 1600°C, making them suitable for applications requiring high temperatures and fire resistance.
2. Insulation: Due to its light weight and porous structure, this brick has good insulation properties, which can effectively reduce heat loss and improve energy efficiency.
3. Corrosion resistance: It has good resistance to chemical erosion and can resist erosion by chemical media such as molten metal or molten glass.
