Many kinds of ceramic composites have been studied to improve the mechanical properties of ceramics. Among them, recently, much attention has been paid to nanocomposites, in which fine particles of the second phase are dispersed in the matrix. In order to realize such a nanostructure, it is important to control the particle structure of starting powder. One of the promising approaches is the use of fine composite particles. In this paper, the preparation and application of fine composite particles were reviewed with emphasis on SiC and Si<SUB>3</SUB>N<SUB>4</SUB>-base composite particles obtained by a vapor phase reaction method and a fluidized-bed CVD method.<BR>It was found that the nanocomposites of SiC-BN and Si<SUB>3</SUB>N<SUB>4</SUB>-BN systems had an excellent thermal-shock resistance due to fine dispersion of h-BN particles.
