摘　　要：研究了以锌粉为原料 ,白碳黑为催化剂 ,高温气相氧化反应制备任意两针夹角为 10 9°的四脚状氧化锌 ( T- Zn O)晶须的条件及形态 .表面能谱证实产物为纯氧化锌 ,X射线衍射结果表明 ,该晶体属六方晶系纤锌矿结构 .扫描电镜研究结果表明 。This paper dealt with the preparing conditions and morphology of tetrapod -like zinc oxide (T-ZnO) whiskers with an angle of 109° between any two legs, which were prepared by vapor-phase oxidation of zinc metal in the air and by introducing white carbon black as a reaction catalyst. The product was pure zinc oxide verified by EDS and XRD patterns of T-ZnO whisker, in which the peaks are sharp with narrow half-widths and can be identified as a wurtzite ZnO structure. Morphology of T-ZnO whiskers was affected greatly by white carbon black as mold catalyst and supersaturations ratio(the fractional pressures of zinc vapor vs pressed air).
