Abstract

The infrared and far infrared (10–4000 cm−1) polarized, single crystal reflectivity of the calcium borate mineral colemanite, CaB3O4(OH)3·H2O, have been measured at room temperature and at several temperatures below the ferroelectric phase transition at approximately 270 K. Over the entire frequency range studied, only minor spectral changes are seen at the ferroelectric phase transition.
