Abstract

<PICT:0973756/C1/1> Solid compound bodies having thermoelectric properties are produced by a process comprising introducing at least two constituents into a reaction vessel, subjecting them under inert atmospheric conditions to a temperature above the melting points of the constituents and of the reaction compound thereof and rapidly solidifying the molten reaction product by applying a cooling liquid to the reaction vessel. The process is particularly suitable for anisotropic thermoelectric materials (e.g. bismuth selenide telluride and bismuth antimony telluride), but may also be used for isotropic materials. Fig. 1 illustrates an apparatus suitable for the production of bismuth selenide tellurides. An evacuated sealed vessel (10), made, for example, of quartz and containing prescribed quantities of bismuth, selenium and tellurium, is suspended in an aperture 12 of a furnace 14. The aperture is lined with a smooth heat conductive ceramic lining 16 with a heating coil 18 disposed around the lining such that the coil is more dense at the bottom than at the top of the furnace. After heating, the reaction vessel 10 is lowered through the high temperature region at the bottom of the furnace directly into a quenching tank 24, whence the reaction compound is solidified. Specified bodies, other than those mentioned above, are indium antimonide, germanium telluride, lead telluride, germanium bismuth telluride and manganese germanium telluride and reference is made to the incorporation of doping impurities in said bodies. Reference has been directed by the Comptroller to Specifications 876,337, 889,480 and 904,878.
