Abstract

YCa4O(BO3)3 (YCOB) crystal was reported to be a potential material for high temperature piezoelectric sensing applications. In this paper, the full matrix of electro-elastic constants, including dielectric permittivities, elastic constants, and piezoelectric coefficients were determined. The relative dielectric permittivities were measured to be ε11T0=9.65, ε22T0=11.80, ε 33T0=9.55, and ε13 T0=0.95, respectively. The piezoelectric coefficients were determined to be d11 = 1.7, d12 = 3.9, d13 = -4.2, d15 = -1.1, d24 = 4.4, d 26 = 7.9, d31 = -0.77, d32 = -2.5, d 33 = 1.4, and d35 = -5.0 pC N-1. In addition, piezoelectric cross-talks of YCOB crystals were investigated, where (XZlw)45°/35° and (YXt)-30° crystal cuts were found to possess pure thickness shear mode, with relatively large effective piezoelectric coefficients, being on the order of d15 = 8.8 and d26 = 9.0 pC N-1, respectively.
