Conclusions

Reflecting power measurements have been carried out for the first time on a considerable number of Geksanit-R specimens of various phase compositions. It has been established that the optical characteristics of specimens composed mainly of BNs match those reported in the literature. Reflection spectra reveal that varying the relative amounts of the BNw, BNs, and BNg phases in specimens brings about changes linked with differences in the character of the reactions of light with their different crystal lattices. Measurement of reflecting power in the IR range of the spectrum (400–2000 cm−1) may be recommended for the semiquantitative determination of the phase composition of Geksanit-R specimens containing not more than 70% of BNs.
