Title: Improvements in piezoelectric resonators
IPC: H03H9/17
Filed: 1949-12-21
Abstract: 663,353. Piezo-electric crystals. RADIO CORPORATION OF AMERICA. Dec. 21, 1949 [Dec. 24, 1948], No. 32769/49. Class 40 (viii). A piezo - electric resonator comprises a polarized body of barium-calcium titanate ceramic in which the ratio of barium titanate to calcium titanate lies in the range 9 :1 to 7: 3 by weight. This gives a lower temperature coefficient of frequency than for pure barium titanate. The graph shows temperatures as abscissµ, the ordinates being deviations from normal frequency for an element designed to resonate at 250 kc/s. Curve (a) is for pure barium titanate and shows a wide deviation of frequency over the temperature range, the discontinuity being at the Curie point. Curve (b) for a 9: 1 barium to calcium titanate shows a slightly rising characteristic over the temperature range 25-70‹, while curve (c), 8: 1 barium to calcium titanate, shows a slightly falling characteristic. Curve (d) for a 7: 3 composition shows a falling and rising characteristic. Within the range 9: 1 to 7: 3 lie the compositions having usefully small, and even zero, temperature coefficients. The elements are made in the form of thin plates moulded under pressure in a steel mould and then fired at 1370‹ C. for four hours. After the application of silver electrodes to the major faces, a polarizing voltage of about 500 volts is applied parallel to the thickness direction. Oscillations at 250 kc. from a valve oscillator are applied to the electrodes to cause longitudinal vibrations at this frequency, the plate being suspended at its midpoint. Alternatively, the electrodes may be mounted on the minor faces to produce thickness vibrations.
