Abstract

Phase equilibrium was studied on the basis of the data of differential thermal, X-ray phase analyzes, as well as measurements of conductivity and density. Phasing diagrams of TlInSe2-CuInSe2 and TlInSe2-AgInSe2 systems were constructed over the entire concentration range. The studied systems were quasi-binary with limited mutual solubility of the components in the solid state. State diagrams were eutectic in nature. The areas of mutual solubility at eutectic temperatures were approximately 3 mol. % on each side in the TlInSe2 system - CuInSe2 and 15 mol. % on the basis of TlInSe2 and 5 mol. % based on AgInSe2 in the TlInSe2 - AgInSe2 system. The solid solutions based on CuInSe2 and AgInSe2, as well as the initial compounds themselves, undergo phase transformations from the chalcopyrite structure to the sphalerite structure. It was found that in these systems limited solid solutions were formed, which were 2.5 mol. % at indoor temperature from TlInSe2 and 1.5 mol. % on CuInSe2 in the TlInSe2-CuInSe2 system and 3 mol. % on TlInSe2, 2 mol. % on AgInSe2 in the TlInSe2-AgInSe system.
