Undoped, 0.5, 3 and 6mol% Dy3+ doped CoNb2O6 powders have been prepared by molten salt method using cobalt nitrate hexa hydrate, niobium oxide, dysprosium oxide and Li2SO4Na2SO4 salt mixture as a flux at 800°C for 4h. X-ray diffraction patterns of the undoped, 0.5 and 3 mol% doped CoNb2O6 samples ex...
