Temperature dependent behaviors of electro-elastic properties of NdCa4O(BO3)3 crystal with monoclinic symmetry
文献摘要：
Rare-earth calcium oxyborate crystals(RECa4O(BO3)3,RECOB,RE:rare-earth elements)are a kind of multifunctional crystal materials.In this work,the temperature dependent behaviors of the electro-elastic constants of NdCOB crystal were investigated over the temperature range of-80-200℃,and their temperature coefficients were evaluated.It is found that NdCOB crystal possesses minimal variation of relative dielectric permittivities(＜3％).The temperature coefficient of frequency for ZY cut with width shear vibration mode is in the order of 0.07×10-4/℃.The temperature coefficients of the elastic compliances are obtained to be in the range of-33.0 x 10-4/℃-32.2×10-4/℃.Particularly,the S44 and S66 were found to show low temperature coefficients of the elastic compliances,i.e.1.0×10-4/℃and-0.4×10-4/℃,respectively,indicating the existence of zero temperature coefficient of frequency crystal cut.Furthermore,the electromechanical coupling factors and piezoelectric coefficients as a function of temperature were studied.The electromechanical coupling factor k26 and piezoelectric co-efficient d26 are determined to be～30.8％and～15.2 pC/N at room temperature,respectively.The large piezoelectric response and zero temperature coefficient of frequency indicate the potential usage of NdCOB crystal for piezoelectric frequency devices over a wide temperature range.
