Properties of (Bi2Sb5Se3Te6I3)1 − x M x (M = Ce, Pr) solid solutions

Properties of (Bi2Sb5Se3Te6I3)1 − x M x (M = Ce, Pr) solid solutions The effect of doping with Ce and Pr on the physicochemical properties of Bi2Sb5Se3Te6I3 has been studied using differential thermal analysis, X-ray diffraction, microstructural analysis, microhardness tests, and density measurements. The results demonstrate that n-type Bi2Sb5Se3Te6I3 dissolves 3.5 at % Ce. The Bi2Sb5Se3Te6I3-Ce system has a eutectic at 10 mol % Ce, which melts at 360°C. The Pr solubility in Bi2Sb5Se3Te6I3 is 4 at %. This system has a peritectic point at 10 at % Pr, with a peritectic temperature of 550°C. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Inorganic Materials Springer Journals

Abstract

The effect of doping with Ce and Pr on the physicochemical properties of Bi2Sb5Se3Te6I3 has been studied using differential thermal analysis, X-ray diffraction, microstructural analysis, microhardness tests, and density measurements. The results demonstrate that n-type Bi2Sb5Se3Te6I3 dissolves 3.5 at % Ce. The Bi2Sb5Se3Te6I3-Ce system has a eutectic at 10 mol % Ce, which melts at 360°C. The Pr solubility in Bi2Sb5Se3Te6I3 is 4 at %. This system has a peritectic point at 10 at % Pr, with a peritectic temperature of 550°C.
