High-performance piezoelectric materials are desirable for piezoelectric sensing applications. In this paper, piezoelectric α-BiB3O6 (BIBO) crystals were explored for high temperature sensing. Dielectric, piezoelectric and electromechanical properties were evaluated by using the impedance method, from which the piezoelectric charge coefficients were determined to be d14 = 10.9, d16 = 13.9, d21 = 16.7, d22 = 40.0, d23 = 2.5, d25 = 4.3, d34 = 18.7 and d36 = 13.0 pC/N, with corresponding piezoelectric voltage coefficients g14 = 122, g16 = 144, g21 = 225, g22 = 538, g23 = 34, g25 = 58, g34 = 165 and g36 = 121 × 10-3 V m N-1 at room temperature (RT). Of particular significance is that the receiving sensitivity of BIBO crystals was found to be 47.2 pm2 N-1, nearly one order of magnitude higher than that of LiNbO3 crystals. Moreover, the BIBO crystals were found to possess a high mechanical quality factor Qm (13000 at RT and >1000 at 600 °C), low dielectric loss (<0.1% at RT and 15% at 600 °C and 1 kHz), high electrical resistivity (∼2.5 × 108 Ω cm at 600 °C) and high temperature stability of piezoelectric coefficients (variations <±10%). All these properties demonstrate that BIBO crystals are promising for piezoelectric sensing over a broad temperature range.
