In this study, the structure of nanocrystalline CaCO-3 was analyzed using TEM, SEM, FT IR and XRD measurements. An unusually narrow %v%-3 band with remarkable blue shift about 40 cm+{-1} in the infrared spectrum was observed. XRD analysis revealed a somewhat large crystallite strain in the nano particle CaCO-3. The strain was possibly related to the weakened lattice vibration. This suggests a preliminary explanation for the abnormal IR assimilation characteristics of nanocrystalline CaCO3 aforementioned.
