摘要

We have investigated conditions for the fabrication of glass-coated wires from the Bi0.5Sb1.5Te3 solid solution by the Taylor-Ulitovsky method and assessed the influence of the coating material and drawing rate on the formation and Seebeck coefficient (thermoelectric power) of wires of various diameters. We have optimized conditions for the fabrication of long wires (up to 1 m) 100 to 250 mu m in core diameter, with geometric parameters stable along their length. The structure of fracture surfaces of the wires has been examined by scanning electron microscopy. Their Seebeck coefficient (a) has been measured in the temperature range 70-420 K. We have obtained wires with 400-K a from 100 to 140 mu V/K by drawing from a melt with an open surface and alpha = 180 mu V/K by drawing from a melt in a closed system (the parent ingot had a = 200 mu V/K).
