N2 - MgZr4(PO4)6 is an Mg2+ ion conductor with an isotropic three-dimensional network structure. In this study, we have examined the effect of pH adjustment on the synthesis of fine MgZr4(PO4)6 powders by a solgel method from Mg(NO3)2·6H2O, ZrCl2O·8H2O, and NH4H2PO4. X-ray diffraction and transmission electron microscopy analyses revealed that controlling the pH at 310.1 during the solgel process was favorable for obtaining fine MgZr4(PO4)6 powder, and it was also beneficial for obtaining almost single-phase sintered MgZr4(PO4)6. Spark plasma sintering of the pH-controlled powder at 1200 °C for 10 min resulted in 94.1 % dense MgZr4(PO4)6, which had an electrical conductivity of 8.38
