Electron Microscopic Studies on Phosphate Binding Processes in the Presence of Iron
Phosphates are widely used as a substitute material for bones and teeth in medical sciences. It is known that phosphate and iron have a strong affinity for each other. In this study, process of formation of iron phosphate was closely monitored using scanning electron microscope equipped with backscatter electron image and energy dispersive X-ray imaging facilities. Different stages of formation of the iron-phosphate material in an environment rich in phosphate and iron were observed. Initial stage of absorbing iron on phosphate-rich substrate is the most important stage of the entire process. X-ray mapping provides strong visual evidence to track down the dispersion of major elements during this process.
