The Densification Behavior for High Energy Ball-Milled Mg and B Powder during the Reaction Sintering Process

摘要:

采用高能球磨Mg／B复合粉体作为前驱粉制备了MgB2超导块材，研究了球磨时间、烧结温度和时间等参数对MgB2超导块材致密度的影响，并理论分析了高能球磨Mg／B复合粉体的反应烧结致密行为。

Abstract:

The bulk MgB2 was prepared by the high energy ball-milled Mg/B precursor powder. The influences of the synthesis parameters, i.e., the milling time, the heat-treatment temperature and the holding time, on the density of bulk MgB2 were investigated. The densification behavior of the Mg and B reaction sinter was analyzed in theory.
