description The present invention relates to a method for making semiconducting pyroelectric material and its equipment, which is characterized by that the semiconducting pyrolelectric material used for making thermoelectric arm in semiconductor thermo-electric device is p-type and n-type semiconducting geode. Said geode is made up respectively by using bismuth, tellurium, selenium and bismuth, antimony, tellurium as raw materials through the processes of melting, droplet condensation and heat treatment. Its special-purpose equipment includes a quartz container with drop nozzle tube, a cooler connected with the quartz container, a gas protection device respectively connected with the quartz container and cooler and a vacuum system. Said invention is simple and easy to operate, and can raise the quality of thermo-electric arm.
