“…It has special application as a raw material in the glass industry and in the production of special ceramics used to immobilize medium-level radioactive wastes for disposal [1] and to protect from neutron radiation [2]. Other uses are in the electrical engineering [3][4][5] in the microfiltration processes of waste and natural water [6] and in the protection of metals [7]. With minor importance, datolite is used as a gemstone [8].…”

The objective of this work is to determine the thermal stability and vibrational spectra of datolite CaBSiO4(OH) and relate these properties to the structure of the mineral. The thermal analysis of datolite shows a mass loss of 5.83% over a 700-775°C temperature range. This mass loss corresponds to 1 water (H2O) molecules pfu. A quantitative chemical analysis using electron probe was undertaken. The Raman spectrum of datolite is characterized by bands at 917 and 1077cm(-1) assigned to the symmetric stretching modes of BO and SiO tetrahedra. A very intense Raman band is observed at 3498cm(-1) assigned to the stretching vibration of the OH units in the structure of datolite. BOH out-of-plane vibrations are characterized by the infrared band at 782cm(-1). The vibrational spectra are based upon the structure of datolite based on sheets of four- and eight-membered rings of alternating SiO4 and BO3(OH) tetrahedra with the sheets bonded together by calcium atoms.
