摘要
采用燃烧合成技术制备多孔碳化硅基复合材料。利用Si、C、Ti体系的放热反应得到SiC/TiC复相陶瓷,其中Ti+C含量要大于25％,否则燃烧反应无法完全进行。燃烧合成产物中含有α—SiC、β-SiC、TiC和少量Si。所研究体系的产物致密度为理论密度的45％～64％。对燃烧合成产物进行了XRD相分析和SEM断口形貌分析。
Porous silicon carbide based composite was prepared by combustion synthesis technique. SiC/TiC composite was gained by combustion reaction of Si, C and Ti system where the content of Ti + C should be larger than 25 % to achieve complete combustion reaction. With 45%～64% relative density, the final products were composed of α-SiC, β-SiC, TiC and little Si. By XRD and SEM, components and structures of porous SiC based ceramics were analyzed.
