Preparation and Pore Size Characteristics of SiC Nanowires/Porous Silica Carbide Composite Ceramic Films
Using glucose and silicon sol mixed solution as precursor,SiC nanowire film was grown on the surface of porous SiC ceramics by carbothermal reduction method to prepare nanocomposite ceramic film.The phase,morphology and pore size characteristics of the samples were analyzed by X-ray diffraction,optical microscope,scanning electron mi-croscope and pore size analyzer.The results show that SiC nanowire film with uniform distribution is grown on the sur-face of SiC with micron pore size at 1 450 ℃ for 6 h,and the nanocomposite ceramic film has narrow submicron pore size distribution.
