湿化学法原位制备(Ti,Zr)C固溶粉体

ON IN SITU PREMRATION OF (Ti, Zr)C SOLID-SOLUTION POWDER BY WET-CHEMICAL METHOD

采用化学共沉淀法原位制备了（Ti，Zr）C均相固溶体粉末.用粒度分析仪和扫描电镜分析粒度大小、分布与形貌.X射线粉末衍射和Raman散射谱表明制得的粉体为均匀的单相固溶体．通过DTA—TG热分析研究了由溶胶混合物形成固溶体的反应过程与机制．

This paper described a kind of technology on in situ preparation of (Ti, Zr)C solid-solution powder with homogenous phase by wet-chemical method. The analysis instrument for particle size and SEM showed the size distribution and morphology of as received solid-solution powder. The components and phase structures wre examined by XRD and Raman spectra. The forming mechanism of the solid-solution powder with homogenous phase was also discussed from the results of DTA-TG Curves.
