Abstract

670,491. Refractory substances. ELECTRO-REFRACTAIRE. Aug. 6, 1947 [June 10, 1943], No. 21452/47. Class 22 A refractory mortar maturing below 800‹C. and capable of withstanding chemical corrosion, e.g. by the molten baths used in the electrolytic production of magnesium contains grains formed of highly refractory material united by a highlyaluminous glass matrix, fines of a binder maturing at the operating temperature of the mortar, and an alkali fluoride. The refractory grains consist of interlocking crystals of mullite and corundum bonded by the glassy matrix, and are prepared by heating silica and alumina together and grinding the products; zircon may also be included. The binder consists of a glass, preferably a borosilicate glass maturing at a temperature of 700-800‹, and constitutes 42-80 per cent of the refractory material. As a temporary binder, sodium silicate solution and sodium silicofluoride are added. Specification 100,738, [Class 56], is referred to.
