Title:
THERMOELECTRIC MATERIAL CONTAINING DISPERSED SHORT THIN METALLIC WIRES AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP3035615
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a method for dispersing short thin metallic wires in a thermoelectric material composed of a magnesium-silicon compound and a thermoelectric material having superior thermoelectric characteristic.
SOLUTION: A magnesium-silicon compound sintered body, in which short and thin metallic wires are uniformly scattered is obtained, in such a way that mixed powder in which the formation of a magnesium-silicon compound is clearly confirmed by X-ray diffraction is manufactured by mechanically alloying magnesium powder, silicon powder, and their inevitable metallic elements at an atomic ratio of 2:1 between magnesium atoms and silicon atoms. Then, after the short and thin metallic wires are mixed in the mixed powder at a rate of 5-30 vol.% with respect to 100 vol.% powder and the powder is dried, the powder is sintered under pressure.
