Preparation and Identification of Calcium Nanoparticles

Abstract

To prepare and identify Ca nanoparitcles. Methods: The Ca nanoparitcles were prepared by precipitation method at different temperatures, buffers or mixing orders. The structure, particle size and morphology of resulting nanoiparticles were characterized by transmission electron microscope (TEM) , particle meter and X-ray photoelectron spectrometer (XPS). Results: It was indicated that granular nanoparticles average diameter 260 nm could be prepared by adding calcium chloride and dibasic sodium phosphate slowly into sodium citrate at low temperature with stirring. The component of nanoparticles was calcium phosphate proved by XPS. Conclusion: The resulting Ca nanoparticles were obtained by precipitation methods.
