Synthesis and Characterization of Monodispersed Spheres of Amorphous Calcium Carbonate and Calcite Spherules

摘要: The isotropic property of amorphous calcium carbonate (ACC) is useful for the controlled synthesis based biomaterials. A simple and efficient strategy monodispersed microspheres ACC reported using a low-temperature precipitation in presence magnesium ions. room-temperature aging this phase yielded superstructures self-assembled calcite crystals. stability precipitated proportional to an increase concentration ions time. with high content was stable one month period at room temperature under dry conditions. aged solution up 48 h. It believed that low facilitated formation spheres ACC. morphological studies characterizations were carried out SEM, FTIR, XRD, electron diffraction, Raman spectroscopy...
