<p>A method of producing a beta -sialon fine powder which comprises using a silane compound represented by the general formula of SiHxCl4-x (0 </= x </= 4) as a Si source, aluminum chloride as an Al source and an ether represented by the general formula of ROR min (R,R min = CyH2y+1, 1 </= y </= 5) as an oxygen source respectively, dissolving them in an organic solvent capable of dissolving them to obtain a solution, introducing ammonia gas into the solution to produce a precipitates, and burning the precipitates in a nonoxidative atmosphere. In the beta -sialon fine powder obtained by the method of the invention, respective elements of Si, Al, O and N are uniformly distributed in a chemical viewpoint. A high density high strength sintered body can be produced even at a relatively low temperature by using the beta -sialon fine powder.</p> |
