Densifiion behavior of high purity SiC by hot …

Densifiion behavior of 99.998% purity SiC by hot pressing without metallic additives was investigated. A theoretical densifiion of 92% was achieved at 2350 °C with 50 MPa in 3 h.The densifiion was more affected by the sintering pressure rather than by the sintering temperature and was independent of initial particle size.

US5863325A - Process for producing high purity …

A process for producing high purity silicon carbide uses a high purity tetraethoxysilane or the like as the silicon source and a novolak-type phenol resin or the like as the carbon source.
