Silica Bricks
Product Information
Silica brick is an acidic refractory material with silicon dioxide as the main component, which has high purity and good refractory properties. Its main component is silicon dioxide (SiO2), the content of which is usually above 93%, and the silicon dioxide content of high-quality silica bricks can reach about 96%. The manufacturing process of silica bricks includes raw material preparation, mixing and homogenization, molding, drying, firing, inspection and packaging. Among them, temperature control during the firing process is crucial and requires precise temperature control to ensure quality.
Features
Strong resistance to acidic slag erosion: Silica bricks have strong resistance to corrosive substances such as acidic slag and molten metal, ensuring their long service life.
High load softening temperature: The load softening temperature of silica bricks is as high as 1640-1670℃, and the volume is relatively stable under long-term use at high temperature.
Good volume stability: At a high temperature of 1600℃, silica bricks can maintain a stable structure and have a low creep rate.
High chemical stability: Silica bricks have good resistance to oxides such as Al2O3, FeO, Fe2O3, but poor resistance to alkaline slag(such as CaO, K2O, Na2O).
