Czochralski Single Crystal Growth of Sr sub(.61)Ba sub(.) sub(3) sub(9)Nb sub(2)O sub(6) for Surface Acoustic Wave Applications

Ferroelectric Sr sub(.61)Ba sub(.39)Nb sub(2)O sub(6) (SBN) single crystals approximately 2 cm. in diameter and 5-6 cm. long have successfully been grown by the Czochralski technique. All the crystals were grown in the (001) direction in argon or oxygen, and it was found that the degree of difficult...

Zusammenfassung:Ferroelectric Sr sub(.61)Ba sub(.39)Nb sub(2)O sub(6) (SBN) single crystals approximately 2 cm. in diameter and 5-6 cm. long have successfully been grown by the Czochralski technique. All the crystals were grown in the (001) direction in argon or oxygen, and it was found that the degree of difficulty of growth increased as the diameter of the crystals increased. Temperature dependence measurements on the poled Z-cut SBN crystals showed that this composition has temperature compensated orientations which make this material useful for surface acoustic wave devices.
