Abstract
PURPOSE:To prevent by-production of glass and to reduce production cost of SiC wiskers by using non-oxidative gas mixed with specified hydrocarbon when a mixture of SiO2 source, C source and NaF source is heated in the non- oxidative atmosphere. CONSTITUTION:A raw material powder 24 mixed SiO2 source, C source and NaF source is packed in a crucible body 21, the non-oxidative gas (N2, Ar, etc.) is introduced to the crucible 20 through an introducing tube 23 and the raw material 24 is heated at a fixed temp. to produce SiC wiskers. At that time, the hydrocarbon gas is mixed with the non-oxidative gas introduced to the crucible 20 in a molar ratio 1/10-2/1 to the non-oxidative gas and, as the hydrocarbon gas, CH4, C2H6, C2H8, C4H10, etc., are used. According to the method, SiO gas generated from SiO2 is converted to SiC wiskers with the added hydrocarbon gas and by-production of glass is prevented.
