Abstract
Various methods for the synthesis of Na2Zr2P2SiO12 ceramics have been investigated. The methods differ by the order of mixing and the use of acetylacetone to decrease the reactivity of zirconium. The homogeneit y of the powders prior to calcination has been checked by P-31 NMR. Th eir reactivity towards crystallization is not drastically different. T he sintering behaviour is much better in powders in which the zirconiu m reactivity has been decreased. The effect of the processing on the r esulting ionic conductivity of the ceramics has been studied.
