Abstract
A borosilicate batch prepared in aqueous medium was investigated by IR spectroscopy. A method was developed for determining the individual sodium borosilicate bands in the presence of the most probable impurities — boric and silicic acids and sodium borate and silicate. The method is based on calculating the absolute degree of difference of the wavenumbers and intensities of the bands. It was found that some of the bands of the five-component batch are indistinguishable with respect to the position in the IR spectrum and the intensity and are unsuitable for analysis. The bands at 653, 1164, 3300, and 3729 cm−1 are indistinguishable with respect to the wavenumbers, but differ in the intensities so that they can be conditionally used for identification of sodium borosilicate.
