Abstract: A novel technique was developed to synthesize porous silica–matrix ceramics from silicon carbide and alumina with an Y2O3 addition, using pine sawdust as a pore former. The porous ceramics were fabried at temperatures of 1300–1500 oC in air by a reaction–bonding process based on two reactions: (1)SiC+2O2→SiO2+CO2 (Oxidation) and (2)2SiO2+3Al2O3→3Al2O3·2SiO2 (Mullitization).

Silicon Carbide | Washington Mills

Silicon carbide (commonly referred to by its chemical formulation of SiC) is a chemical compound comprised of silicon and carbon that results in extremely hard (9 on the Mohs scale) iridescent crystals.

20/5/2008· For the f-SWCNT/silica compacts, there is a significant reduction of about 75%, 69%, and 67% in the specific surface area for C1, C2 and C3, respectively, compared to the f-SWCNT/silica monoliths. The densifiion promoted by high pressure is responsible for these results, and the difference obtained in the surface area is probably due to the low concentration of f-SWCNTs in the …
