Effect of calcination conditions on phase formation and particle size of zinc niobate powders synthesized by solid-state reaction

Effect of calcination conditions on phase formation and particle size of zinc niobate powders synthesized by solid-state reaction

A columbite-like phase of zinc niobate, ZnNb2O6, has been synthesized by a solid-state reaction via a rapid vibro-milling technique. The formation of the ZnNb2O6phase in the calcined powders has been investigated as a function of calcination conditions by TG-DTA and XRD techniques. Morphology, parti...
