Preparation of needlelike Sr0.5Ba0.5Nb2O6 particles using molten SrCl2–BaCl2 salt

  Needlelike Sr0.5Ba0.5Nb2O6 powder particles were prepared from SrCO3, BaCO3, and Nb2O5 in the presence of a mixture of molten SrCl2 and BaCl2. When the composition of the mixture of oxide and carbonate was fixed to be SrCO3:BaCO3:Nb2O5 = 1:1:2, the phase and morphology of the product particles were dependent on the composition of molten salt. The exchange reaction, BaO + SrCl2 = BaCl2 + SrO, enriched Sr in the oxide phase. The relation between the compositions of the salt mixture and the reaction product was determined, and needlelike Sr0.5Ba0.5Nb2O6 particles were obtained by using the molten salt containing 18 mol % SrCl2.
