Abstract

Operation at temperatures well above ambient is desired for applications such as smart structures integrated within aircraft and space vehicles. Piezoelectric yttrium calcium oxyborate single crystal Y Ca₄ O(B O₃)₃ (YCOB) was found to exhibit no phase transition until its melting temperature around ∼1500 °C. The temperature characteristics of the resonance frequency, electromechanical coupling, and dielectric permittivity were studied in the temperature range of 30-950 °C for different orientations. The electrical resistivity at 800 °C was found to be greater than 2× 108 cm. Together with its temperature independent electromechanical coupling factor (∼12%) and engineered resonance frequency behavior, these make YCOB crystals excellent candidates for sensing applications at ultra high temperatures.
