Abstract
The structure and granularity of biological origin aragonite from abalone shell during wet grinding in a ball mill were studied with X-ray diffractometer, with morphology studied by scanning electron microscope (SEM). It is shown from the results that the particle sizes of aragonite decreased with grinding time, so did the X-ray diffraction (XRD) peak intensities, while the full widths at half maximum increased. A calcite XRD peak with low intensity and great width was observed in nearly all the samples with various grinding time, whereas the intensity of the peak increased obviously after grinding time 300 min. It is shown from the SEM results that the size of aragonite dropped with grinding time until it reached 20 nm and then kept constant, while that of calcite dropped first and then rose at the minimum about 10 nm until to the constant size as in aragonite. It was observed that the mineral content obtained from XRD show an obviously change that the calcite increases while aragonite decreases, which indicated the occurring of a polymorphic transformation of aragonite into calcite.
