A novel method to synthesize low-cost magnesium fluoride spheres from seawater

Abstract Magnesium fluoride (MgF 2 ) is widely used as optical materials. A novel method for low-cost manufacturing of magnesium fluoride micro spheres from Baltic seawater was studied. The method focuses on a novel strategy of utilizing seawater. This study will facilitate large-scale production of MgF 2 micro spheres. This method provides a prototype which can synthesize low-cost inorganic spheres from seawater.
