The ash by-products from combustion or gasification of western US coals have chemical and mineralogical characteristics that lend themselves to utilisation in ceramic materials. Laboratory and pilot-scale fabrication of four such materials has been studied. Cyclone slag from four lignite-fired power plants and a dry scrubber ash has been fabricated into mineral wool insulation in a pilot-scale cupola. Extended and fired mixtures of fly ash, clay and ground glass have produced ceramics with very high flexural strength. Ceramic glazed wall tiles utilising fly ash in place of clay have been prepared and shown to meet most specifications for fired clay tile. Both fired and unfired dry-pressed brick containing 100% western fly ash have met ASTM specifications for fired clay brick.
