Диаграмма состояния системы фторид калия–трифторид брома

KBrF 4 построена диаграмма состояния системы KF–BrF 3 в области высоких температур.The authors have studied experimentally the phase equilibriums in the system potassium fluoride–bromine trifluoride in the range of concentrations from 0 to 0,7 of KF mole fractions and have formed the phase diagram corresponding to this part of the system. The dependence of potassium tetrafluorobromate solubility in bromine trifluoride on temperature was determined. The composition and temperature of eutectic in the range of phase diagram with low content of potassium fluoride were defined experimentally. By the results of thermogravimetric analysis of KBrF 4 decomposition the authors have formed the phase diagram of the system KF–BrF 3 in the range of high temperatures.
