Title:
A magnesium silicon composite material and a manufacturing method for the same, thermoelectrical conversion material using the composite material, thermoelectric conversion elements, and a thermoelectrical conversion module
Document Type and Number:
Japanese Patent JP6029256
Kind Code:
B2
Abstract:
Provided is a magnesium-silicon composite material which contains Mg 2 Si as an intermetallic compound imposing no burden on the environment, is suitable for use as a material for thermoelectric conversion modules, and has excellent thermoelectric conversion performance. The magnesium-silicon composite material has a dimensionless figure-of-merit parameter at 866K of 0.665 or larger. This magnesium-silicon composite material can have high thermoelectric conversion performance when used in, for example, a thermoelectric conversion module.
