Silica Refractories
Silica refractories were first created in 1822 in the United Kingdom from Ganister (caboniferous sandstone) or Dinas sand.Quartz, tridymite, and cristobalite are examples of crystalline modifications of silica, as well as an under-cooled melt known as quartz glass. Each of the crystalline alterations has a high and low temperature form that can …

Traditionally, silica bricks are manufactured using quartzite. Silica fused grains, based on chemically pure quartz sands, are also used today. For brick production a small amount of a sulphite solution is added as a pressing aid while lime is used as the binder and mineraliser. This lime reacts with the fine silica fraction forming β-2CaO-SiO 2
