Changsha 410076, China）Abstract: In order to study the slagging characteristics of boiler carborundum combustion liners during pulverized coal stream combustion, the slag samples of pulverized coal stream combusting experiments were investigated by optics microscope and X-ray diffraction.

摘 要：采用光学显微镜和X射线衍射等方法对煤粉气流燃烧过程在碳化硅质卫燃带上的渣样进行测试，并对渣样的形貌及结晶特性、渣样成分与碳化硅之间的高温烧结特性进行分析。

The experimental results show that the content of SiC in RBSC increases with carbon content while α-SiC is chosen as a filler. However, the residual carbon would appear in specimens when the carbon content exceeds 30% by weight. Using carbon felt, the reaction-formed SiC particles are small and uniform in size and distribution. However, when carbon felt is impregnated with phenol resin, the reaction-formed SiC is nonuniform in size and distribution. X-ray diffraction shows that the fabricated RBSC is composed of α-SiC,β-SiC, and free Si. The polytype of SiC is related to the reaction-heat during sintering.

结果表明：选用α-SiC+C粉的混合物作为生坯，SiC相的体积分数随生坯中wC的增加而增加，但过大的wC将使硅化后的试样出现残碳；选用碳毡作为生坯，反应烧结碳化硅的显微组织特点是C／Si反应生成的碳化硅颗粒均匀细小，并呈线状分布在游离硅中；浸渍过树脂的碳毡硅化处理后的显微组织特点是反应生成的碳化硅颗粒粗大且呈不均匀分布。X射线衍射结果也表明，反应烧结碳化硅陶瓷由游离Si、α-SiC、β-SiC组成，试样中不同晶型碳化硅的出现与C／Si反应的放热过程有关。
