Synthesis of silicon carbide through the sol-gel process …
Silicon carbide (SiC) was synthesised from silicon alkoxides and various carbon sources. Tetraethoxysilane (TEOS), methyltriethoxysilane (MTES) and a mixture of TEOS and MTES were hydrolysed in the presence of phenolic resin, ethylcellulose, polyacrylonitrile (PAN) and starch to incorporate the gel into the carbon source in the silica network. The gel thus obtained was carbonized …
Tungsten carbide | chemical compound | Britannica
Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600 C (4,700 F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400 –1,600 C (2,550 –2,900 F).
