Abstract
894,307. Thermo-electric devices. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Nov. 11, 1959 [Nov. 12, 1958], No. 38255/59. Class 37. The production of elements for a thermoelectric unit includes the step of compressing a semi-conductor compound crystalline body so as to distort its shape. The material may consist of Bi2Te3, Bi2Se3, Bi2S3, Sb2Te3, or Sb2Se3 or solid solutions thereof, or of PbTe, PbSe or PbS or solid solutions thereof. In one example, an N-type conductivity element is produced by compressing at 350 C. a body consisting of 75 mol. per cent Bi2Te3, 25 mol. per cent Bi2Se3 and 0.02% weight of CuBr. A P- type element is produced from a body consisting of 60 mol. per cent Bi2Te3, 40 mol. per cent Sb2Te3 and 0.2% weight of CuSe. Fig. 1 shows the starting material 1 in the form of a cylinder of smaller diameter than that of the compression chamber formed between rams 4 and 5 and wall 3. The pressing chamber and body alternatively may be of rectangular shape. Fig. 3 shows a conveyer belt 9 carrying the press tools through lock 10 into vacuum container 11 where they are heated in furnace 13, pressed between dies 14 and 15, passed through lock 16 and cooled in chamber 17 in a current of nitrogen from pipe 18. The bodies may be produced by directionally cooling a melt of the material. The process results in improved thermo - electric elements, quality being measured as a function of thermoelectric force, and thermal and electrical conductivities.
