Effect of calcination conditions on phase formation and particle size of nickel niobate powders synthesized by solid-state reaction
The solid-state mixed oxide method via a rapid vibro-milling technique is explored in the preparation of single-phase nickel niobate (NiNb2O6) powders. The formation of the NiNb2O6phase in the calcined powders has been investigated as a function of calcination conditions by TG-DTA and XRD techniques...
