Determination Of The Water Content Of Alkali Lime Silica Glasses By Ir Spectroscopy Using Nuclear Reaction Analysis For Calibration

Systematic IR and NRA investigations were performed for two series of glasses with very different water contents. The glasses had the composition (in mol%): 16R20.10Ca0.74Si02(R=sodium, potassium). The IR absorption coefficients of the OH bands were found to be linearly correlated with the total hydrogen content obtained by the NRA measurements. Using the hydrogen concentration values from NRA, the total water contents were calculated and so-called practical IR extinction coefficients were deduced.
