Abstract

102,507. Lecesne, N. April 29, 1914, [Convention date]. Alumina.-Corundum is obtained by burning with compressed air in a shaft furnace an intimate mixture of bauxite and anthracite or other fuel, so as to form and immediately burn aluminium carbide, the introduction of compressed air being continued after the fusion to burn out the carbon. Preferably, crude bauxite containing its natural moisture is mixed with an anthracite without grinding and charged direct into the furnace, disintegration of the charge and intimate mixing of the materials occurring automatically in the furnace. Water may be added to the bauxite if necessary to ensure this disintegration in the furnace. A temperature such as that at which alumino-thermic mixtures burn is attained, silica and iron being volatilized from the charge; although the product may contain some particles of silica and iron or magnetic iron oxide. The furnace operation may be of limited duration, for instance three hours, in order to leave a small quantity of finely-divided carbon in the product. The product, after cooling, is ground, mixed with an agglomerant, for instance hydrated bauxite, or a mixture of quartz, quicklime, and water, moulded and baked to form refractory bricks, crucibles, grinding-wheels, &c. The carbon remaining in the corundum may furnish sufficient additional heat during the baking to fuse the added raw bauxite, forming a solid block.
