Spark Plasma Sintered Si3N4/TiN Nanocomposites Obtained by a Colloidal Processing Route
2016
Journal of Nanomaterials
Ceramic Si3N4/TiN (22 vol%) nanocomposites have been obtained by Spark Plasma Sintering (SPS). Our colloidal processing route allows obtaining dispersed nanoparticles of TiN smaller than 50 nm avoiding the presence of agglomerates. The nanostructured starting powders were obtained by using a colloidal method where commercial Si3N4submicrometer particles were coated with anatase TiO2nanocrystals. A later nitridation process led to the formation of TiN nanoparticles on the surface of Si3N4. A
