Abstract
This thermoelectric material manufacturing method includes the steps of: preparing a powder from an at least binary thermoelectric alloy (AxB1-x) intended to be used as a matrix; mixing the powder with nanoparticles of pure metal (M) intended to form inclusions in the matrix; and submitting the mixture to a step of sintering at an adapted temperature resulting in the forming, in the matrix, of nanometric inclusions of composition MaAb and/or MaBb.

16. A thermoelectric material manufacturing method, comprising the steps of:
-
preparing a powder from an at least binary thermoelectric alloy (AxB1-x) intended to be used as a matrix; mixing the powder with nanoparticles of pure metal (M) intended to form inclusions in the matrix; submitting the mixture to a step of sintering at an adapted temperature, comprised between the temperature necessary to reach 90% of the maximum densification and the melting temperature of the metal (M) and of the alloy (AxB1-x), during which nanometric inclusions of composition MaAb and/or MaBb are formed in the matrix. - View Dependent Claims (17, 20, 21, 22, 23, 24, 25, 26, 27)
