【 摘 要 】

The process of rhenium and fluorine interaction in the interval of temperatures from 200 °C up to 600 °C has been investigated. Influence of fluorine charge, fluorination square and temperatures on the process efficiency and fluorine use efficiency have been determined. Presence of two areas of process behavior, namely kinetic and diffusion has been demonstrated. It was shown that in the course of fluorination a mixture of hexafluorides and heptafluorides was formed. Dependence of rhenium fluorides composition on temperature has been determined.
