Growth of ferroelectric lead metatantalate single crystals

Growth of ferroelectric lead metatantalate single crystals

Liquidus relations in the “Pb(BO2)2”-PbTa2O6, Pb(VO3)2-PbTa2O6, and Pb2V2O7 —PbTa2O6 systems were studied in order to find solvents for growing ferroelectric lead metatantalate single crystals below 1300‡C. PbO-V2O5 melts were shown to be suitable solvents for growing lead metatantalate crystals wit...

Zusammenfassung:Liquidus relations in the “Pb(BO2)2”-PbTa2O6, Pb(VO3)2-PbTa2O6, and Pb2V2O7 —PbTa2O6 systems were studied in order to find solvents for growing ferroelectric lead metatantalate single crystals below 1300‡C. PbO-V2O5 melts were shown to be suitable solvents for growing lead metatantalate crystals with both rhombohedral and tetragonal potassium tungsten bronze structures. Ferroelectric PbTa2O6 crystals with a Curie temperature of 265‡C were grown from vanadate fluxes.
