Review of Research on the Thermoelectric Material ZnSb ...

The thermoelectric material ZnSb has been studied intensively in recent years and has shown promising features. The other zinc‐antimonide compound, Zn4Sb3 has remarkable low thermal conductivity, but it is accompanied with phase transitions at moderate temperature and has inherent stability problems. Compared to that, ZnSb is relatively phase stable and has a relative high charge carrier ...

High Critical Current Density MgB2 | IntechOpen

The combined process improves the connectivity of MgB 2 grains and the compactness of the superconducting core in wires, which induces high critical current density in zero field. The flux pinning force can also be improved by dopants for magnetic field application.

Thermoelectric performance of Si80Ge20 ... - ScienceDirect.com

Si 80 Ge 20 − x Sb x based alloys were synthesized employing high energy ball milling and induction hot pressing with change in milling time and Sb content. With increasing milling time, the grain size decreases and the elements become more evenly distributed for both the as-milled powder and the hot pressed samples.
