| Abstract: | MgB_2 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 tempera- ture in the synthesis process were discussed.The results show that MgB_2 phase has synthesized without other impurities such as MgB_4.The particle size is small and the MgB_2 is easy to decompose. |
| Keywords: | magnesium diboride powder self-propagating high-temperature synthesis superconductor |
