Crystal growth of Mn15Si26

Abstract

The crystal growth of manganese silicide with a Si/Mn ratio near 1.73 was performed by the Bridgman method followed by chemical transport. The Bridgman as grown boule was observed to have a lamellar structure identified to be composed of a MnSi precipitate and a Mn 15 Si 26 matrix. The chemical transport was carried out by using crushed grains of the Bridgman boule as starting material and CuCl 2 as transport agent. Homogeneous single crystals of Mn 15 Si 26 having an average linear size of 0.5 mm were grown on the colder zone. The crystals were identified by X-ray technique as well as by electron probe micro analysis.
