Abstract
1330526 Silicon carbide whiskers ELEKTROSCHMELZWERK KEMPTEN GmbH 5 Nov 1970 [5 Nov 1969] 52689/70 Heading C1A SiC whiskers, e.g. having a length of 5-50 mm. and a diameter of 1-3 Ám, are prepared by heating Si or SiO 2 , optionally containing carbon and a doping agent, in an atmosphere of a carbon-containing vapour at a temperature of 1000-1700‹ C. in the presence of one or more of the elements of groups IIIa or IVa or a halide or oxyhalide of such an element, other than metallic lanthanum, as catalyst. The preferred catalyst is LaCl 3 or HfCl 3 . The carbon containing vapour may be CO, a hydrocarbon (e.g. CH 4 , C 2 H 6 or C 6 H 6 ), an organosilicon compound, (e.g. organosilane, halogenated organosilane, or an organosiloxane). The vapour phase may also contain a halogen, N 2 or H,.
