[en] A thermographic study of Yb, Se and YbSe interaction with iodine has been made which is of interest to elucidate possibilities of crystallization by the method of chemical transport reactions using iodine as a transporting agent (the static version). Experiments have been conducted at 20-1000 deg C in vacuum of approximately 1,10^-4 mm Hg. On the basis of data obtained the formation of a compound of Se with iodine in the gas phase under conditions of the experiments has been suggested. The onset of interaction between Yb and Se has been established (approximately 300 deg C), as well as of YbSe with iodine (approximately 160 deg C). Using data of the differential-thermal analysis, some recommendations on realization of the chemical transport in the system YbSe-I₂ are proposed
