摘要
采用聚二甲基硅烷(PDMS)和二茂铁合成了聚铁碳硅烷(PFCS)。以有序氧化硅凝胶小球为模板、PFCS作先驱体,经过先驱体的渗入、不熔化、陶瓷转化和除去模板,制得氮气吸附法(BET)比表面积为703.46 m2/g的有序多孔含铁碳化硅SiC(Fe)磁性陶瓷。
A polyferrocarbosilane （PFCS） was synthesized from polydimethylsilane （PDMS） and ferrocene. The ordered-porous Fe-containing SiC ceramic with BET specific surface area of 703.46 m^2/g was prepared. The preparing process included the formation of silica template, PFCS precursor infiltration into the template, curing of the precursor, pyrolysis of the cured preceramic polymer and etching of the silica template. The ceramic showed some magnetic properties.
