Abstract Nasicon ceramics of formula Na3Zr2Si2PO12 were prepared from two systems, namely NH4H2PO4-Na2CO3-SiO2-ZrO2 and Na3PO4-SiO2-ZrO2. The partial reactions and sequence of reactions was studied using differential thermal analysis and X-ray diffraction analysis. Kinetic restraints to completeness of reaction are indicated and sodium oxide volatilization is shown to occur. The rate-determining partial reaction involves zirconia and a sodium phosphosilicate intermediate.
