Refractory industrial material Britannica
The workhorse of the clay-based refractories are the so-called fireclay materials. These are made from clays containing the aluminosilicate mineral kaolinite (Al 2 Si 2 O 5 OH 4) plus impurities such as alkalis and iron oxides. The alumina content ranges from 25 to 45 percent.

Silica RefractoriesIspatGuru
Silica refractories were first produced in United Kingdom in 1822 from Ganister (caboniferous sandstone) or from so called Dinas sand. Silica occurs in a variety of crystalline modifications e.g. quartz tridymite and cristobalite and also as an under-cooled melt called quartz glass. The crystalline modifications each have a high and low

Aluminium SilicateTechnology Products Market
Silica-alumina is also known as alumino-silicate(s). It is an oxide-like combination of aluminium silicon and oxygen and it has a major component of kaolin and clays. Inorganic Chemistry by Swaddle calls the group of minerals aluminosilicate when some of the Si4 ions in silicates are replaced by Al3 ions.

Impact of alternate fuels on industrial refractories and
The cause of failure of a refractory brick used in an industrial burner firing an alternate fuel is described. The burner which was used to calcine CaSO/sub 4/ in a lime-type kiln was fired with No. 6 residual oil. The refractory lining in the burner was constructed of aluminosilicate brick castable and mortar in contact with one another.
