Abstract: Al2O3-SiO2-CaF2-P2O5 glass powder was prepared by liquid synthesis with AlCl3、Na2SiO3、CaCl2、NaF and Na5P3O10 as starting-reagents.The influences of reagents concentration on characteristics of the powders were studied by XRD、EDAX and TEM methods.The results show that the reactant concentration has little effect on the chemical composition and crystal state of the powders,which are amorphous compounds containing O、F、Al、Si、Ca、P atoms and constituted by near spheroidic nano particles,but the reacta...
