Abstract
The method for the direct determination of fluorine in glass on a solid by wide-line NMR (60 MHz) is studied.
The results are summerized as follows.
1) As the water content of a powdered sample was increased, intensity of fluorine resonance decreased.
2) As the amounts of paramagnetic impurities increased, intensity of fluorine NMR signal increased enormously and the plateau regions were in the range more than 0.06% for Fe2O3.
3) R. F. saturation factor and spectral line width of 19F signal on fluoride system differed with glasses.
This spectroscopic method can be applied to routine analysis when amounts of other components of glasses do not vary.
