摘要: 利用自蔓延高溫合成法成功制備了MgB₂粉末．通過熱力學計算、X射線衍射圖譜分析了各相生成的先后順序及轉化關系,探討了合成反應產物中的相組成、MgB₂的分解溫度等．結果表明,自蔓延高溫合成法能制備無MgB₄等雜質相的單相MgB₂,且晶粒細小易于分解．

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.
