摘要：

The chemical reactions between CuSe, SnSe and ZnSe and their enthalpies in molten CdI2 in closed vacuum ampoules were investigated. Differential thermal analysis (DTA) was used for the determination of the temperatures of processes occurring in the studied mixtures. X-ray diffraction and Raman spectroscopy were performed to discover the phase changes in the long-term annealed samples at higher than peak temperatures in DTA. The occurring chemical reactions and their enthalpies were derived. The recrystallization of CZTSe in CdI2 was investigated. The results confirmed the formation of Cu2SnSe3, Cu2SnSe4, CdSe, Cu2CdSnSe4, Cu2ZnSnSe4, and Zn1-xCdxSe compounds and solid solutions.
