Molten Salt Synthesis of a Complex Perovskite, Pb(Fe0.5Nb0.5)O3

摘要: Pure, single-phase stoichiometric Pb(Fe0.5Nb0.5)O3 (PFN) powders were successfully formed by molten salt synthesis using mixtures of NaCl and KCl salts. Lower temperatures shorter times (1/2 h at 800°C) needed for singlephase PFN formation from salts relative to those required solid-phase methods (4 1000°C). A systematic study indicating the effects process parameters, such as temperature, time, amount flux with respect starting oxides, on mechanism its resulting powder characteristics is reported. The particle size increased increasing temperature; rate increase was greatest above 900°C, which close melting point PbO. are spheroidal, free aggregates, sintered good densities low 1000°C.
