Abstract
A sodium magnesium calcium hydrogen monophosphate Na3Mg1-x CaxH(PO4)(2 ), yH(2)O; x = 0.05 and x = 0.20 was synthesized and characterized by various physical techniques. Its morphology depends on the synthesis t emperature and on the evaporation rate. Samples were characterized by X-ray diffraction, and analyzed by IR and Raman vibrational spectrosco py and impedance spectroscopy techniques. The effect of partial substi tution of calcium for magnesium on the electrical conduction has subse quently been undertaken. It shows an unusual high conductivity and dec reased activation energy corresponding to the mobility of H3O+ ions of the hydration water.
