Thermoelectric properties of nanocrystalline PbTe synthesized by mechanical alloying
(2010)
In this work, nanocrystalline lead telluride powder was synthesized from high-purity elements by mechanical alloying by means of a planetary ball-milling procedure. The milling medium was tungsten carbide, and the diameter ...
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 ...
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, ...
