Abstract

A composition comprises a granular aggregate of sintered magnesia, chromite or mixtures thereof and, on a dry weight basis 2 to 6% w/w clay, up to 2% w/w magnesium sulphate or sodium silicate of mixtures thereof, 0.5 to 1.5% w/w ferric sulphate or aluminium sulphate or ferrous chloride and 0.2 to 0.6% w/w of sodium perborate, sodium percarbonate, or sodium perchlorate or mixtures thereof. The composition can be used to produce ceramic coatings on refractory materials by mixing it with water, allowing the mixture to stand and then applying it to a refractory substrate, drying it and then heating it to a high temperature.
