Abstract
1,160,610. Magnesite brick. DRESSER INDUSTRIES Inc. 29 Dec., 1967 [9 Jan., 1967], No. 59184/67. Heading CIJ. Burned magnesite brick comprising, by weight, at least 90% MgO, at least 1 % CaO + SiO 2 , and up to 3% Fe 2 O 3 + Cr 2 O 3 + Al 2 O 3 , and having a CaO : SiO 2 ratio of 2 : 1 to 5 : 1 is impregnated with an amount of soluble phosphate such that the brick has a CaO : SiO 2 : P 2 O 5 ratio falling with the area ABCDE shown in Fig. 1. Suitable soluble phosphates are the sodium phosphate glasses, the sodium phosphate salts and phosphoric acid. In the examples burned bricks are impregnated with a 25% by weight solution of a sodium metaphosphate glass and dried at 250 F. for 10 hours. X-ray diffraction patterns indicate the formation of calcium sodium silicophosphate or calcium silicophosphate solid solutions which bond the brick.
