METHOD FOR THERMOELECTRIC MATERIAL PRODUCTION FOR THERMOELECTRIC GENERATOR DEVICES ON BASIS OF LEAD TELLURIDE Russian patent published in 2018 - IPC H01L35/16 

FIELD: electricity.

SUBSTANCE: production of the thermoelectric material for thermoelectric generator devices on the basis of lead telluride of the prescribed properties and composition is carried out by the batch primary components solvent sealing in the alundum melting pot with constant stirring by means of the acoustic waves impact with a frequency of 22-24 kHz and with a capacity of 400-600 W within 30-50 minutes. The fusion temperature of the batch is 880-910°C. Afterwards, the liquid-alloy is sustained within 15-20 minutes at a temperature of 900-930°C, then it is cooled down at a speed of 100-150 deg/min, and the alloy homogeneization is carried out within 10-12 hours after the crystallisation at a temperature of 600-700°C.

EFFECT: providing availability of the lead telluride thermoelectric material and solid solutions on its basis in the atmospheric environment under high-temperature agent of fusion, the method simplification, thus providing for the key distinction from the known technical solutions.
