Crystallization of highest manganese silicide MnSi1.71–1.75 from tin-lead solution-melt

A new version of controlled synthesis of single-crystal and textured highest manganese silicide (HMS) MnSi1.71–1.75 is considered. This thermoelectric crystallizes on the surface of molten metals (Sn, Pb), which forms a floating lens. Such a configuration produces a narrow oriented zone with a sharp temperature gradient (zone melting). Simultaneously, Sn and Pb serve as solvents, as a result of which HMS partially recrystallizes in the form of microcrystallites in the bulk of HMS-Sn or HMS-Pb solution-melt.
