Mechanisms of the formation of a bulk superconducting phase Mg[B.sub.2] at high temperatures

The structure of Mg[B.sub.2] samples synthesized from magnesium flakes and a boron powder at temperatures of 900-1000°C has been investigated. It has been found that the samples have "dendrite-like" and layered structures formed as a result of the dissolution of solid boron in liquid magne...

Description
Summary:The structure of Mg[B.sub.2] samples synthesized from magnesium flakes and a boron powder at temperatures of 900-1000°C has been investigated. It has been found that the samples have "dendrite-like" and layered structures formed as a result of the dissolution of solid boron in liquid magnesium followed by crystallization. The obtained structures have been analyzed within the theoretical concepts of crystallization from melt.
