  • Sintering Behavior of Spark Plasma Sintered SiC with Si

    Nov 25, 2017Sintered SiC pellets were prepared by SPS process using the mixture with different ratio of micron-sized SiC powder and nano-sized Si-SiC composite particle as a sintering additive. At a fixed ratio of micron-sized SiC and nano-sized Si-SiC (90:10), the relative density and Vicker's hardness increased with increasing sintering temperature and

  • What is Sintering

    Sintering is the process of forming and compacting a material by pressure and heat. Sintering is a major step in powder metallurgy and ceramics processing. The driving force for sintering is the reduction in total particle surface area. Surface energies are larger in magnitude than grain boundary energies. Sintering is usually carried out below
