    Abstract

    Si3N4-based composite powders have been synthesized by vapor phase and liquid phase processes. Nano-sized Si3N 4-TiN composite particles were formed by the vapor phase method, in which TiN nanocrystallites were included in amorphous Si3N 4 particles. The composite powder was also formed by the liquid phase method, where Si and Ti complex imide powders were prepared in an organic solvent and decomposed by heating. Si3N4-TiN nanocomposites were fabricated by hot pressing of the composite powders. The Si3N4-TiN composites were also fabricated by in-situ process from amorphous Si3N4 and Y2O 3-TiO2-AlN additive. In all processes, rod-like Si 3N4 grain growth was stimulated by TiN inclusion.
