Semi-Silica Brick
Description
Semi-silica brick can be divided into fired bricks and unfired bricks. Unburned bricks mostly use water glass as a binder. The firing process of bound bricks is roughly the same as that of clay bricks. The firing temperature is higher than that of clay bricks, generally at 1350~1410 ℃.
Features
- Anti-acid slag.
- High temperature structural strength.
- Good volume stability.
