Abstract

<p>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 sol–gel method from Mg(NO3)2·6H2O, ZrCl2O·8H2O, and NH4H2PO4. X-ray diffraction and transmission electron microscopy analyses revealed that controlling the pH at ∼10.1 during the sol–gel 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 × 10−4 S cm−1 at 800 °C.</p>
