The temperature coefficient of frequency (TCF) was investigated in monoclinic NdCa4O(BO3)3 (NdCOB) piezoelectric crystals over the temperature range of -140 °C to 200 °C. A zero TCF characteristic was achieved for the (ZXw) 15° crystal cut, with turnover point at 20 °C. The electromechanical coupling k26 and piezoelectric coefficient d26, in shear vibration mode, were determined to be 25% and 13.5 pC/N, respectively. The zero TCF crystal cut, large coupling factor and high piezoelectric coefficient, together with a high mechanical quality factor (Q > 10,000), demonstrate NdCOB crystals promising candidates for bulk acoustic wave resonators over a wide temperature range.
