ABSTRACT

The structure of MgB2 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. More... »
