Mg2Si/MgO nanofibers were synthesized by the heat treatment of amorphous SiO2 nanofibers in Mg vapor, and their morphological and structural properties were then investigated. Well-aligned Mg2Si/MgO nanofibers with high density were synthesized, which preserves the general morphology of the original SiO2 nanofibers. The morphology and crystalline quality of Mg2Si/MgO nanofibers depend on the reaction temperature. This reaction provides a low cost method to synthesize nanoscale thermoelectric materials with high crystalline quality to enhance thermoelectric properties. [DOI: 10.1380/ejssnt.2012.297]
