Silica Brick

Silica brick not only has the characteristics of high strength at high temperature and high refractoriness under load (1620~1680℃), but also has the characteristics of strong resistance to acid slag erosion and long-term use at high temperature without deformation. The residual expansion of silica bricks when heated will make the joints of the masonry tightly closed, ensuring good air-tightness and strength of the masonry structure.
