Vibrational Raman spectroscopy was used successfully for the quantitative determination of the cubic and monoclinic phases of zirconia. Pressed pellets with known composition were prepared using monoclinic and cubic powders from different manufacturers and were used as standard mixtures. An intensity ratio plot of the 617-cm[sup [minus]1] band, which is attributed to the presence of both phases, to either the 177-cm[sup [minus]1] or 476-cm[sup [minus]1] monoclinic band against the inverse monoclinic molar fraction ([chi]) yielded a straight line which was described by ratio = 0.11[chi][sup [minus]1] + 0.26 and ratio = 0.12 [chi][sup [minus]1] + 0.29, respectively. The method was found to be independent of the origin of the powders.
