Influence of the parameters of a fluorine–hydrogen mixture on the flame propagation velocity

Measurements were made of flame propagation velocities in atmospheric-pressure fluorine-hydrogen mixtures with different compositions. It was shown that, for the same stored energy, diluting a mixture with a diatomic gas such as nitrogen, instead of with monatomic gases, or adding the polyatomic gas SF₆ sharply reduced the combustion rate and increased the threshold fluorine pressure at which combustion was converted into detonation under the conditions being studied.
