Silica is a refractory ceramic which is widely used in the steel and glass industries. Silica bricks are prepared by kiln-firing quartz of low impurity content at a temperature of 1450°C, thereby converting at least 98.5% of it into a mixture of the more ‘open’, less dense forms, tridymite and cristobalite.

1982.1.1 Properties of Silica Bricks. Typical properties of low-alumina silica bricks are given in Table 1. It will be seen that these have a silica content of 96.3% and an alumina content of 0.3%. The lime (1.8%) has little effect on the refractoriness, and adds greatly both to the ease of brickmaking and the strength of the product.
