Abstract: This experiment used MTES as raw materials,HCl as catalyzers,and C2H5OH as solvent to prepare SiO2 sol under certain condition. Then it mixed bamboo charcoal powder,silica powder and SiO2 sol in terms of definite proportion,and resulted in the formation of SiC ceramic in static argon atmosphere. FT-IR,SEM-EDS and XRD were employed to characterize the physico-chemichal structure changes,microstructure and phase changes during bamboo charcoal-to-SiC ceramics conversion. And the adsorption and resi... More
