Features
SiC ceramics is generally prepared at high temperature of 1200–2000ºC. We are able to prepare SiC at around 700ºC by using Na. Nano-powder of beta-type SiC was obtained from a mixture of Si and carbon powders in a Na melt. SiC porous ceramics were synthesized by heating mixtures of Si powder and carbon black at 700–900ºC in Na vapor. Biomorphic cellular SiC ceramics were formed by heating carbonized woods at 700 ºC with a Na-Si melt.

Targeted Application(s)/Industry
Applications : SiC porous ceramics are used in a wide range of applications, such as filters for gas or molten metal, diesel particle filters, catalysis supports, and light-weight structural materials.
Industry : Ceramic Engineering
