摘要
室温下用PMS(polymethylsilane,聚甲基硅烷)和SbCl_3合成了新型液态SiC陶瓷先驱体锑掺杂聚硅烷(Antimony-substitutedPolysilane,APS)。Sb元素的引入形成了部分支化结构,提高了APS的陶瓷收率。经320℃固化后,APS陶瓷收率为91%。1250℃烧结产物主要成分为β-SiC和Sb金属。
A liquid SiC precursor, namely, antimony-sustituted polysilane (APS) of a high ceramic yield, is presented. The APS was synthesized from the reaction of PMS and SbCl3 at room temperature. The introduction of Sb increased the crosslinking degree of APS. After crosslinked at 320℃, the ceramic yield attained 91%. The pyrolysed product consisted of β-SiC and metal Sb. The APS precursor would have potential applications for making inorganic materials.
