Abstract: Abstract The lead-free polycrystalline NaNb1−xVxO3 (NV: 0.00 ≤ x ≤ 0.06) samples are prepared by standard solid-state reaction technique. Room temperature X-ray diffraction (XRD) analysis suggests an orthorhombic crystal structure for NV ceramics. Field emission scanning electron microscopy (FE-SEM)… read more here.
