The structure and morphology as well as oxidation resistance of the powders were studied by X-ray diffractometry(XRD),transmission electron microscopy(TEM),BET,chemical analysis,gas analysis,differential thermal and thermogravimetry analysis.

• 用XRD、TEM、BET、化学分析、氧含量分析、DSC-TGA等测试手段研究了粉体的相组成、形貌、粒度分布、比表面积和氧化特性等。
