“…The temperature of the AgInSe2 ordering is 11 degrees lower than the melting temperature (for a visual demonstration it is shifted somewhat down in Figure 2). According to the obtained data, the temperature of ordering was 1045 K, which complies with the results of the research works [1,[5][6][7][8][9]).…”

“…The solid solutions based on CuInSe2 and AgInSe2, like the initial compounds themselves, undergo phase transformations and chalcopyrite structures into the sphalerite structure. According to the obtained data, the temperature of the phase transition (temperature of ordering) in CuInSe2 was 1083 K, which also complies with the results of the research works [1,8,9]. Melting points CuInSe2 and AgInSe2 were 1263K and 1056K, respectively.…”

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.

According to the data of differential thermal, X-ray phase analyzes, as well as measurements of conductivity and pycnometric density, phase equilibriums were studied and phasing diagrams of TlInS2-CuInS2 and TlGaSe2-CuGaSe2 systems were created in the entire concentration range. The studied systems are quasi-binary with limited mutual solubility of the components in the solid state. The interaction in the TlGaSe2-CuGaSe2 system occurs with the formation of one eutectic and one peritectic points, in the TlInS2 system-CuInS2 with the formation of one eutectic and two peritectic points. Eutectic at 1048 K corresponds to 18 mol. % CuGaSe2 and at 945 K 17-mol. % CuInS2. Solid solutions based on CuGaSe2, CuInS2, like the initial compounds themselves, undergo phase transformations. It is found that in these systems limited solid solutions are formed, which make up 1.5 mol. % at indoor temperature on TlGaSe2 and 0.5 mol. % on CuGaSe2 in the TlGaSe2-CuGaSe2 system, as well as 1.5 mol. % on TlInS2 and 0.5 mol. % on CuInS2 in the TlInS2-CuInS2 system. The nature of the interactions of the components makes it possible to assign the presented phasing diagrams to type VI according to Rooseboom.
