| Abstract: | T Thermal chemical vapor phase reation i;first applied to the synthesis of nanometer SiC-Si_3N_4 composite ultrafine powder successfully and ernphasis is focued On the quantitative effect of reation condi-tlons on the composition,size,shape and crystallinity of resulting particles.The SiC-Si_3N_4 ultrafine powder is in size of narrow ranges,equiaxial morphology and a nonagglomerated state. The smallest average particle size of SiC-Si_3N_4 powders prepared under the different conditions is 89A. |
