Influence of calcination conditions on phase formation and particle size of indium niobate powders synthesized by the solid-state reaction
A wolframite-type phase of indium niobate, InNbO4, has been synthesized by a solid-state reaction via a rapid vibro-milling technique. The formation of the InNbO4phase in the calcined powders has been investigated as a function of calcination conditions by TG-DTA and XRD techniques. Morphology, part...
