Pulse plasma synthesis and chemical bonding in magnesium diboride

摘要

A new way of preparation of magnesium diboride by pulse plasma technique is described which results in microcrystalline powder material. The superconducting transition with an onset at 387.3 K was observed in good agreement with the results of other groups obtained on samples prepared by conventional techniques. The phase exists near the nominal composition without a significant homogeneity range. The chemical bonding in magnesium diboride was analyzed by means of electron localization function.
