Abstract

1363138 Finely divided oxides INSTITUT METALLURGII IMENI A A BAIKOVA AKADEMII NAUK SSSR and GOSUDARSTVENNY NAUCHNO-ISSLEDOVATELSKY I PROEKTNY INSTITUT REDKOMETALLICHESKOI PROMYSHLENNOSTI 26 Aug 1971 40031/71 Headings C1A and C1N Finely divided oxides are produced by oxidizing an element or halide thereof at 1000- 6000‹ C. with a gas stream containing at least 5% by volume dissociated oxygen. A gas containing oxygen in at least 5% excess, is passed through an induction discharge into a reaction zone into which the element or halide is introduced at a point where the dissociated oxygen is uniformly distributed in the stream. In examples, TiCl4, Fe powder, and Si powder were oxidized to give TiO2, gamma-Fe2O3 with particles 500-2000 Š in size, and SiO2 with an average particle size of 0À02-0À04 Á. Oxides of Zn, Al, Cu, Ti, B, and Ge may be made similarly by oxidation of the elements.
