摘要：

We investigated the properties of a SiC membrane on alumina, derived from polycarbosilane. The thickness of the deposited SiC layer was approximately 1 mu m. The topmost layer, having a thickness of approximately 0.6 mu m, comprised high-purity SiC. The 2.8 mu m thick layer present below it appeared to consist of SiO2. The contact angles between the SiC membrane and molten alumina at 973 K and 1373 K were approximately 67% and 86% of that between non-modified alumina and molten alumina. (C) 2012 Elsevier B.V.
