| Abstract: | High ordered CaCO3 multilayer-stacking assemblies were easily synthesized by a gaseous diffusion route.Scanning electron microscopy (SEM),powder X-ray diffraction (XRD),Fourier transform infrared spectroscopy (FT-IR) were employed to characterize the samples.Results indicate that the concentration of L-aspartic acid and reaction time have great influence on both the morphology and crystal phase of the produced CaCO3.The mechanism of L-aspartic acid concentration how to affect the morphology and crystal of c... |
