Characterization of Magnesium Silicide Stannide Powder for use in Selective Laser Melting


Keywords: , , ,

This study examines magnesium silicide stannide (Mg2Si0.4Sn0.6) powder, a thermoelectric material optimal for high temperature applications. Powder morphology and particle size distribution were analyzed through optical microscopy and the image analysis software FIJI. The ability to spread was assessed across 100 μm and 500 μm thick grooves using two rolling techniques, as well as a razor blade. Flowability was examined through the measurements of, angle of repose, angle of spatula, and compressibility. Mg2Si0.4Sn0.6 was characterized to establish the feasibility of using this powder in the selective laser melting process.
