The article presents the results of a study of the heat capacity of V 1-X Fe X O 2 , temperatures of phase transformations in the semiconductor phase have been determined. The phase transition diagram of the V 1-X Fe X O 2 system is presented. Values of the change in the entropy of phase transformations for V 1-X Fe X O 2 materials are determined. It was determined that the values of the change in the entropy of the metal-semiconductor phase transition decrease with iron concentration increasing. The results of differential thermal analysis, temperature dependences of electrical resistivity, magnetic susceptibility, and thermoelectric coefficient are presented for the FeV 2 O 6 compound. It was determined that the FeV 2 O 6 compound is a semiconductor in the temperature range from 100 К up to 400 К.
