Abstract

142,721. British Thomson-Houston Co., (General Electric Co.). Aug. 19, 1919. Refractory substances containing magnesia.-A refractory substance is formed of a mixture of magnesia which has been fused, crystallized, and crushed, and magnesia which has been heated to a lower temperature and will further shrink on heating, and which may be obtained by heating a magnesium compound such as magnesium carbonate or hydrate to about 700‹ C. A binding agent such as magnesium sulphate or chloride, or ferrous sulphate is added. The composition, moistened with water, is pressed into position as a furnace lining or moulded to form bricks, crucibles, &c., which are heated up slowly to decompose the binding agent, and ultimately to 1700- 1900‹ C. or higher.
