The investigetion of the pr2se3-ti2se join is internal section of the Pr-Tl-Se ternary system

With extensive possible technological applications, semiconductor systems have become an important field of study today. Physical and chemical characterization of new semiconductor materials synthesized differently from the literature plays a significant role. Such characterizations provide preliminary information about the prior material to application. Pr and Tl chalcogenides are perspective materials, with semiconductor quality.The present study aims to establish the phase diagram of the Pr2Se3-TI2Se system using physical-chemical analyses (XRD, DTA, microstructure and microhardness properties (MSA and MHA), density determination, chemical properties etc. analyses); to identify new semiconductor phases, in the solid solution field, and stability of compounds; and to explore doping concentration, crystal transition, if any, its hardness, density, and certain chemical properties. This project will also attempt to determine the particular appropriate in the industrial sectors for the useing of the produced chalcogenides in accordance with the results of their physical and chemical characterization. The system contains a ternary compound. This melting behavior has been studied for the first time. The compound PrTISe2 melts congruently at 13900C; respectively. The The Pr2Se3-TI2Se join is a quasi-binary internal section of the Pr-Tl?Se ternary system is a eutectic type. At room temperature, the TI2Se-based solid solution extends to 3.0 mol % Pr2Se3; the Pr2Se3 solubility practicaly has not been investigated yet.
