  • Method for producing Heusler-based phase thermoelectric material using an amorphous phase precursor and device using Heusler-based phase thermoelectric material produced by the method
    Patent number: 12029121
    Abstract: Disclosed is a method for producing a Heusler-based phase thermoelectric material using an amorphous phase precursor. More specifically disclosed is a method for producing a powder or bulk thermoelectric material having a microstructure including a Heusler-based phase with a thermoelectric effect by crystallization of an amorphous phase precursor prepared by a non-equilibrium processes. Also disclosed is a device using a Heusler-based phase thermoelectric material produced by the method. The method largely avoids the efficiency problems of conventional methods, including low productivity in scaling up caused by long annealing time, high annealing temperature, and contamination during nanopowder production, achieving improved process efficiency. In addition, the method enables efficient production of a thermoelectric material having a nano-sized microstructure that is difficult to produce by a conventional method.
