Abstract
PURPOSE: To obtain powdered SiC suitable to a raw material for preparing a sintered material in high purity and yield on an industrial scale, by reacting an inorganic silicon compound containing a halogen with NH3, and then reacting the resultant reaction product with a carbonaceous substance in a nonoxidizing atmosphere.
CONSTITUTION: An inorganic silicon compound containing a halogen, e.g. SiCl4, is reacted with NH3 at a molar ratio between the compound and NH3 of 0.1W5 at 400W1,600°C for a reaction time of 30W0.1sec. If the amount of the NH3 is lower than the lower limit, the rate of the reaction is low. If the amount is higher than the upper limit, the reaction operation is difficult due to the deposition of NH4Cl. If the reaction temperature is lower than the lower limit, NH4Cl is deposited. If the temperature is higher than the upper limit, too much energy is required, and a reactor material is limited to a material usable in an atmosphere containing a chloride at a high temperature. If the reaction time exceeds 30sec, the reactor is enlarged to an unnecessary size. If the reaction time is shorter than 0.1sec, the reaction will not proceed substantially. The resultant powdery reaction product is take out in an atmosphere of N2, etc. and reacted with a carbonaceous substance in the same atmosphere at about 1,400W1,800°C.
