Title:
熱電材料の製造方法
Document Type and Number:
Japanese Patent JP6390662
Kind Code:
B2
Abstract:
A method for producing a thermoelectric material, comprising: mixing an Sn powder and a powder containing a first dopant element to obtain a first mixed raw material, heating the first mixed raw material at a temperature allowing for mutual diffusion of Sn and the first dopant element to obtain a first aggregate, pulverizing the first aggregate to obtain a first powder, mixing an Mg powder, an Si powder, and the first powder to obtain a second mixed raw material, heating the second mixed raw material at a temperature allowing for mutual diffusion of Mg, Si, Sn and the first dopant element to obtain a second aggregate, pulverizing the second aggregate to obtain a second powder, and pressure-sintering the second powder, and wherein the first dopant element is one or more elements selected from Al, Ag, As, Bi, Cu, Sb, Zn, P, and B.
