A novel method to synthesize low-cost phosphate-based particles from natural water

Calcium phosphate (CaP) and magnesium phosphate (MgP) are widely used as biomaterials. A novel method for low-cost manufacturing of calcium phosphate spheres and magnesium phosphate micro particles was studied. The method focuses on novel strategies of utilizing seawater and lake water. In the natural water, the molar ratios of Mg/Ca are constant. The morphologies of the particles are determined by ratio of Ca/P. This simple method provides a prototype to synthesize low-cost inorganic spheres with natural water, which facilitate large-scale production.
