Abstract
Macroporous SiC and BN with a different degree of ordered pore arrays were prepared by infiltrating liquid precursors into sacrificial crystalline array of monodisperse colloidal silica spheres in range 70∼500nm. The polymethylsilane and polycarbosilane were used as the SiC precursors, and borazine was used as the BN precursor The silica template was subsequently etched off after pyrolysis in an argon atmosphere at 1200∼1300 °C. An alternative nanotublar morphology of stoichiometric SiC was produced using alumina membranes as templates.
