Solid-state synthesis and thermoelectric properties of Sb-doped Mg 2Si materials
(2013)
Sb-doped magnesium silicide compounds have been prepared through ball milling and solid-state reaction. Materials produced were near-stoichiometric. The structural modifications have been studied with powder x-ray diffraction. ...
Fabrication of nanocrystalline Mg 2Si via ball milling process: Structural studies
(2012)
In this work, nanocrystalline Mg 2Si material was fabricated via wet ball milling process using n-hexane as process control agent. Milling parameters, with emphasis on milling time and ball size, and conditions were studied ...
Solid-state synthesis of Mg 2Si via short-duration ball-milling and low-temperature annealing
(2013)
In this work, a short duration ball-milling of elemental Mg and Si followed by a thermal treatment is suggested in order to synthesize magnesium silicide via solid-state reaction. The formation of magnesium silicide was ...
Effect of silicon nitride/oxide on the structure and the thermal conductivity of CoSi nanocomposites
(2017)
In this work, the fabrication of nanocomposites with silicon nitride/oxide into the thermoelectric matrix of cobalt silicide is presented. The different concentrations of nano-Si3N4 were intentionally introduced by mechanical ...
Effect of Bi-doping and Mg-excess on the thermoelectric properties of Mg2Si materials
(2014)
In this work, Bi-doped magnesium silicide compounds were prepared by applying a combination of both, short-time ball milling and heating treatment. The effect of Mg excess was also studied, aiming towards further improvement ...
Structural features of ball-milled nanostructured K2Bi 8Se13 thermoelectric material
(2011)
In this work, K2Bi8Se13 material was ball-milled in order to develop nanostructures through the modification of structural features. Structural changes during ball-milling were followed by powder X-ray diffraction measurements, ...
