Abstract
282,402. Singer, F. Dec. 17, 1926, [Convention date]. Abrading-materials consisting of double silicates, similar in type to naturally-occurring plagioclase compounds, are produced by reacting the oxides, carbonates, sulphates, silicates or aluminates of divalent metals (such as magnesium, calcium, barium, strontium, zinc, and divalent iron), or mixtures thereof, with alumina and silica at temperatures below the fusion point of the mixture, and preferably at temperatures at least 50‹ C. below the fusion point, the value of the latter being taken as the softening point of the Seger-cone. The proportions of the mixture employed may be such as to correspond to the formula RO. Al2O3-2SiO2. Alumina is preferably introduced as oxide, hydroxide, silicate, double silicate free from alkali, or aluminate, and silica as quartz sand, alkaline-earth silicate, aluminium silicate, or double silicate free from alkali. In an example a mixture comprising 10-12 parts magnesium oxide, 33-43 parts alumina, and 40-50 parts silica is reacted at a temperature somewhat above 1.000‹ C.
