Abstract：

Starch,　prepared　by　heating　starch　suspension　at　85°C,　and　tetraethoxysilane　(TEOS)　have　been　allowed　for　a　sol-gel　reaction　to　prepare　starch-SiO2　hybrids　gel.　The　SiC　was　synthesized　via　carbothermal　reduction　of　dried　starch-SiO2　hybrids　gel.　Dried　starch-SiO2　hybrids　gel　and　as-prepared　products　were　characterized　by　TGA,　XRD,　SEM　and　low　temperature　N2　adsorption-desorption　measurement.　The　results　showed　that　high　crystalline　β-SiC　with　average　crystalline　size　of　50　nm　could　be　synthesized　at　950°C　under　dynamic　vacuum　condition.
