Abstract
PURPOSE: A piezoelectric single crystal material more improved than rock crystal, comprising lead titanate as a base, obtained by substituting partly a rare earth element for Pd and Zr, Nb, Cd, etc. for Ti.
CONSTITUTION: Reagent, e.g., lead titanate and PbO, K2NdF5, K2TiFe, InF3, MnF2, as raw materials, are melted in the platinum crucible 3, and the base plate 4 is placed on the platinum base plate holder 6 at the tip of the upper alumina rod 7. Here, the base plate 4 is immersed in the melting material 5 by the motor 9 to carry out epitaxial growth. The temperature in the furnace is controlled by the signal from the thermocouples 10 and 10. The base plate 4 is heated and cooled by a given program to finish the growth of crystal. Thus a piezoelectric crystal material shown by a specific chemical equation can be obtained. X in the formula is one of rare earth elements, y is one or two or more of Zr, Nb, In, etc., x is 0<x≤0.7, and y is 0<y≤0.5.
