Descrição: dc.descriptionWe have studied the mineral kornerupine a boro-silicate mineral by using a combination of scanning electron microscopy with energy dispersive analysis and Raman and infrared spectroscopy. Qualitative chemical analysis of kornerupine shows a magnesium-aluminium silicate. Strong Raman bands at 925, 995 and 1051 cm-1 with bands of lesser intensity at 1035 and 1084 cm-1 are assigned to the silicon-oxygen stretching vibrations of the siloxane units. Raman bands at 923 and 947 cm-1 are attributed to the symmetrical stretching vibrations of trigonal boron. Infrared spectra show greater complexity and the infrared bands are more difficult to assign. Two intense Raman bands at 3547 and 3612 cm-1 are assigned to the stretching vibrations of hydroxyl units. In the infrared bands are observed at 3544 and 3610 cm-1. Water is also identified in the spectra of kornerupine.-
