Özet:
The phase equilibrium in the AsSe-MnSe system has been studied using physicochemical characterization techniques (differential thermal analysis, X-ray diffraction, microstructural analysis, microhardness tests, and density measurements), and its phase diagram has been mapped out. The system is shown to be a pseudobinary join of the ternary system Mn-As-Se. At AsSe: MnSe = 1: 1, the system contains a compound of composition MnAsSe(2), which melts incongruently at 750A degrees C. The glass-forming region extends to 15 mol % MnSe. We have examined the crystallization behavior of the glasses. Solid AsSe dissolves up to 2 mol % MnSe, and solid MnSe dissolves up to 2.5 mol % AsSe.
