Phase and chemical characterization of perovskite nickel niobate ceramics fabricated via a precursor method

Perovskite relaxor ferroelectric lead nickel niobate (PNN) ceramics were fabricated by using B-site precursor method, in which columbite-NiNb 2O6 was employed as key precursor. It has been found that optimization of sintering condition can successfully lead to highly dense PNN ceramics. Although XRD...
