method and mechanical mixing method, and were pressureless liquid-phase sintered to prepare silicon carbide ceramic. The effects of adding methods on the sintering behaviour, mechanical properties and microstructure of silicon carbide ceramic were analyzed. The results show that at the sintering temperature of 1950℃, silicon carbide ceramic, with SiC/(Al2O3+Y2O3) composite powder by mechanical......

Formation and in vitro induction ability of apatite nanobelt coating on silicon WU Zhen-jun(吴振军)1, YUAN Jian-min(袁剑民)2, LI Wen-sheng(李文生)1, REN Yan-qun(任艳群)1, CHEN Zong-zhang(陈宗璋)1 1... September 2009; accepted 20 April 2010 Abstract: Apatite coating with nanobelt structure was fabricated on single crystal silicon by a two-step method of electrodeposition at 1.0-2.0 mA/cm2 with DC power......
the reaction path and further increase the conversion of silicon carbide at a lower temperature. It is considered that the assistant reduction consists of three steps: vaporizing and melting of silicon, formation of silicon monoxide, and synthesis of silicon carbide. The morphology of the synthesized SiC powders through the silicon assistant method can be affected apparently by the experimental temperature......
