Method for synthesizing a BixSb2-xTe3 thermoelectric nanocompound and the thermoelectric nanocompound thereof

摘要

PURPOSE: A method for manufacturing BixSb2-xTe3 nanocompound thermoelectric materials and the nanocompound thermoelectric materials manufactured by the same are provided to increase a thermoelectric performance index by synthesizing BixSb2-xTe3 nanocompounds for a low temperature through a wet chemical process. CONSTITUTION: Bi-Sb solutions are made by injecting a Bi and Sb precursor to solvents(A1). Te solutions are made by injecting Te powder to mixture of acid and solvents(A2). BixSb2-xTe3 reactants are made by mixing the Bi-Sb solutions with the Te solutions(A3). BixSb2-xTe3 nanoparticles are obtained by filtering and drying the BixSb2-xTe3 reactants(A4). The BixSb2-xTe3 nanoparticles are thermally processed(A5).
