Abstract

A composition, forming a melt having a wide solidification range and which is superheated in an electric furnace above the complete melting temperature and then cast in a mould in which solidification results in a crystallization particularly resistant to corrosion and erosion in a basic medium, contains in per cent by weight magnesia at least 90; alumina 1 to 6; lime 2 to 7; silica proportioned that the CaO/SiO2 ratio is from 0.2 to 1.9: 1; iron 0-3 (calculated as Fe2O3) and less than 0.5 of minor impurities.
