Novel sintering method for preparing thermoelectric material

The invention belongs to the technical field of industrial waste heat energy recycling, and particularly relates to a novel sintering method for preparing a thermoelectric material. The method comprises the following steps: step 1, preparing thermoelectric material sintering precursor powder, wherein the powder synthesis mode of the thermoelectric material is not limited; 2, sintering the block sample by using an oscillation hot pressing process; step 3, carrying out test pretreatment on the sintered block sample; step 4, carrying out comprehensive characterization test on the sintered sample; the thermoelectric block sample is synthesized through a novel oscillation hot pressing sintering technology, on one hand, the alternating load of oscillation hot pressing in the sintering process promotes particle rearrangement, gas residues in powder particle gaps are removed, the sample porosity is reduced, and the conductivity of the material is improved; on the other hand, by applying oscillating force, the grain s
