自蔓延高温合成MgB2粉末

MgB2 powder synthesized by a self-propagating high-temperature method

    摘要
  • 摘要: 利用自蔓延高温合成法成功制备了MgB2粉末．通过热力学计算、X射线衍射图谱分析了各相生成的先后顺序及转化关系,探讨了合成反应产物中的相组成、MgB2的分解温度等．结果表明,自蔓延高温合成法能制备无MgB4等杂质相的单相MgB2,且晶粒细小易于分解．

     

    Abstract: MgB2 powder was successfully synthesized by a self-propagating high-temperature method. Thermodynamic calculation and XRD analysis were used to investigate the powder's synthesizing order and transforming relationship between different Mg-B phases. Phase composition and decomposition temperature in the synthesis process were discussed. The results show that MgB2 phase has synthesized without other impurities such as MgB4. The particle size is small and the MgB2 is easy to decompose.
