Abstract

NASICON (Na₃Zr₂Si₂PO₁₂) has been prepared by a sol-gel route. The progress of the reaction in the liquid has been monitored by means of ³¹P NMR spectroscopy. The dependence of phase formation and sintering behaviour of films and powders on sol-gel reactions and heat treatments was investigated. X-ray diffraction measurements showed the formation of monoclinic NASICON phase from 800 °C for powders and from 900 °C for films together with free ZrO₂. An almost pure NASICON phase was observed in powders calcined at 1000 °C. Sintered pellets showed densities up to 98% of theoretical value. The microstructure of the samples was analysed by scanning electron microscopy.
