Abstract

Abstract Hexacelsian has been determined by infrared spectroscopy with KBr discs and K 4Fe(CN) 6 as internal standard. A KBr particle size of <40 μm gave better homogenization of the sample-KBr mixture than a particle size in the 40–70 μm range. For determinations of hexacelsian in synthetic samples containing amorphous phase or celsian, calibration curves were constructed. A least-squares fit yielded correlation coefficients of 0.998 and 0.997.
