High temperature piezoelectric properties of yttrium calcium oxyborate single crystals

Journal Article


Abstract


  • The piezoelectric single crystal yttrium calcium oxyborate, YCa4O(BO3)3, was studied as a function of orientation and temperature. The resistivity of Y-cut samples was found to be 2.7 × 107 Ω cm at 950 °C, three orders of magnitude higher than langatate crystals. The electromechanical coupling k26 and piezoelectric d26 were found to be 22% and 10 pC/N at room temperature for (ZXw)-30°-cut samples, respectively, maintaining similar values at elevated temperature of 950 °C, exhibiting temperature independent behavior. Furthermore, the highest temperature frequency coefficient was obtained in (ZXw)-33°-cut samples, being -91 ppm/K. The temperature independent piezoelectric properties, together with the high resistivity and mechanical quality factor Q (~2000 at 950 °C), suggest the YCOB crystal to be a good candidate for high temperature sensing applications. © 2010 WILEY-VCH Verlag GmbH & Co.
