Abstract
Si3N4/SiC nanocomposite has been prepared using a chemical reaction be tween Si3N4 powder and phenolic resin as a commercial polymer. The pol ymer was an effective source that could provide free carbon for fabric ation of the nanocomposite. In mixture containing both the Si3N4 powde r, which contained some amount of SiO2, and the polymer, SiC nanoparti cles were considered to be formed by direct reaction between carbon an d Si3N4/SiO2. Sizes of the formed SiC particles were in the range of 1 0-200 nm. The SiC particles were well dispersed in the matrix. (C) 199 8 Elsevier Science S.A.
