ABSTRACT
A range of clays (predominantly blends of alumina and silica) high in silica (40 – 80%) and low in iron oxide (2 – 3%) produce fireclay refractory products which will withstand high temperatures without deformation. Dense products have high flame resistance, while the insulating lower-density products are suitable for flue linings. White glazed fireclay is typically used for urinals, floor channels, industrial and laboratory sinks.
