Abstract

Spherical polycrystalline particles of Na4Zr2Si3O12 (NZS) have been prepared by a mist pyrolysis technique with alkoxide ethanol solution. Firing the precursor particles, obtained by pyrolysing at 550 °C, yielded the NZS with the highest S/N ratio and the least second phase at ∼ 1000 °C. Each spherical particle with an average size of ∼ 0.5 μm was composed of primary particles of 0.1 μm diameter after firing. Comparing the particle formation process with the sol-gel, alkoxide pyrolysis and the aqueous solution processes, it would appear that the primary particle size of the mist-pyrolysed NZS depends on the size and residual alkyl group content of the precursor polymers.
