Fabbrica dei refrattari di Rongsheng
Semi-silica brick is an aluminum silicate refractory product with an alumina (Al2O3) content of 15-30%, and is a semi-acidic refractory brick. Semi-silica bricks generally use refractory clay containing quartz sand, pyrophyllite, refractory clay or kaolin beneficiation tailings as raw materials. Semi-silica bricks shrink less during firing, because at 1250°C, the quartz in the raw material is converted into cristobalite, and the volume expands, which partially offsets the shrinkage produced during clay sintering. The manufacturing process of semi-silica bricks can be divided into two types: fired or not fired. The manufacturing process of fired bricks is basically the same as that of clay bricks; non-fired bricks are mostly made of water glass as a binder.
