Abstract

1360827 Production of powdered materials using induction discharge INSTITUT METALLURGII IMENI AA BAIKOVA AKADEMII NAUK SSSR 5 Aug 1971 [6 Aug 1970] 36815/71 Heading B1X [Also in Divisions C1 C7 and H5] Powdered materials are produced by a chemical reaction or physical process in the presence of a vibrating gas, by passing the gas through an induction plasma and modulating the amplitude or frequency of the current in the power supply so that the gas is caused to vibrate, and feeding a gas, liquid, or solid into this gas. The vibrating gas may be a reactant or inert. Self-oscillating triodes or tetrodes may be used to effect anode or grid modulation. The following reactions may be effected: O 2 + TiCl 4 , SiCl 4 , ZrCl 4 or AlCl 3 to give the oxide (Ex 1); Si+SiO 2 comminuted and fed into Ar to give SiO (Ex. 2); air + finely divided Fe, Al, or Cu, give the oxide (Ex 4); hydrocarbon +halide of Ti, Hf, Nb, Ta, Si, Zr, W, Mo, Th or U, to give the carbide (Ex 5); NH 3 + chloride of Al, B, Si or Zr, to give the nitride (Ex 6); SiO 2 + carbon fed into Ar to give SiC (Ex 7); CH 4 decomposed to carbon black (Ex 9); H 2 + chlorides of Nb and V to give intermetallic compounds (Ex 10); and decomposition of phosphate ore (Ex 11). In Ex 3, fine materials are spheroidised by feeding them into a stream of air or Ar, e.g. Al 2 O 3 , MgO, SiO 2 , ZrO 2 or TiC. In Ex 8, nitrile is fed into Ar to give pigmentary TiO 2 .
