SiC掺杂对中间相碳微球组织的影响
Effect of SiC Dopant on Microstructure of Mesocarbon Microbeads Body
【摘要】 以Tween 80为分散剂,分别以丙烯酰胺和N,N′-亚甲基双丙烯酰胺为单体和交联剂,采用凝胶注模工艺,经过1000℃的埋碳烧结工艺,分别制备了掺杂SiC的中间相碳微球凝胶注模素坯和烧结体.研究SiC加入量对素坯和烧结体的影响.结果发现,当加入w(SiC)达到15%时,SiC具有明显的催化石墨化的效果.
【Abstract】 Using Tween 80 as dispersant,acrylamide as monomer,bisacrylamide as crosslinking and SiC as dopant,mesocarbon microbead(MCMB) green bodies were prepared with gelcasting and sintered bodies at(1 000 ℃) in carbon embedding condition.The effect of SiC dopant on microstructure of MCMB green and sintered bodies was investigated.The results show that the effect of catalytic graphitization with 15% SiC is apparent.
