Title:
THERMOELECTRIC CONVERSION MATERIAL, PROCESS FOR PRODUCING THERMOELECTRIC CONVERSION MATERIAL, AND THERMOELECTRIC CONVERSION MODULE
Document Type and Number:
WIPO Patent Application WO/2016/039372
Kind Code:
A1
Abstract:
The thermoelectric conversion material (10) according to an embodiment comprises a plurality of matrix particles (22) and nanoparticles (30). The matrix particles (22) have a crystalline structure. The nanoparticles (30) comprise an oxide and are present at the boundaries between the matrix particles (22). The nanoparticles (30) contain at least one of the elements constituting the crystalline structure. When the thermoelectric conversion material (10) is examined with a scanning electron microscope to acquire an image of a cross-section thereof having an area of 6 μm × 4 μm, then the group of particles in the image which are composed of matrix particles (22) and nanoparticles (30) have an average particle diameter (d), which is an average of the equivalent circular diameters, of 100-1,000 nm.
