Overview of Silicon Carbide

Unfortunately, this silicon carbide powder is difficult to sinter due to the low diffusion coefficients inherent in the material. Regular sintering conditions usually result in large amounts of neck growth without densifiion, a process exacerbated by the volatization of SiO 2 to SiO + O 2 which condenses at the neck region between particles.
