Abstract

520,889. Agglomerating mineral substances; artificial stone. DITERICHS, W. Oct. 28, 1938, No. 31233. Convention date, Oct. 30, 1937. [Classes 22 and 70] Granular crystalline mineral substances are agglomerated by a binder which yields on firing crystals which are identical, isomorphous or compatible with the crystals of the substance being agglomerated. The granular substances may be abrasives such as emery, corundum or other forms of alumina, silicon, horon or other carbides or nitrides, bauxite, magnesite, chromite, zirconia, iron or chromium oxides, or oxides of beryllium, molybdenum, tungsten titanium, vanadium or thorium, or natural or artificial silicates. The binder consists of silica gel or other mineral gel with water and metallic oxides or salts. In an example, a product consisting of granular rhombohedral alumina agglomerated by crystalline rhombohedral magnesium tourmaline is prepared by mixing a solution containing magnesium chloride, aluminium hydrate mixed with phosphoric acid, sodium silicate, silica gel and boric anhydride. The mixture is ground, moulded, dried slowly up to 260‹C., heated slowly to 1260‹C., and then to 1370‹C. at which it is kept for some time and then cooled slowly.
