STRUCTURAL INVESTIGATIONS IN THERMOELECTRIC MATERIALS
Abstract
Two further alloys in the system BiSbTe were investig ted in order o complete our evaluation bracketing Alloy 68 compositions. The systems selected were Bi28Sb48+xTe134-x and Bi12Sb70+x Te158-x. In general, the two alloys seem to fall in line chemically with Alloy 68 in that effects of compositional changes on the electrical properties become minimized as the antimony content of the alloy increases. This is in line with our concepts of poising. Introduction of selenium into the antimony-rich alloy leads to an overall degradation of the figure of merit. Inv stiga ions were continued in the analogous vanadium alloy system of Alloy 68. The compositions turned out to be nearly degenerate and further work was discontinued. Substitution of arsenic for antimony was carrie out in n alloy system patterned after Alloy 68, but experimental difficulties have to d te precluded any re sonable r sults. Elimination of bismuth from this syste leads to alloys in the series SbAsTe which have proven to be p-type materials with low Seebeck coefficients. (Author)
