Piezoelectric ceramic material with wide temperature adaptation range, sensor and preparation method and application of piezoelectric ceramic material
The invention belongs to the technical field of piezoelectric materials, and relates to a piezoelectric ceramic material with a wide temperature adaptation range, a sensor and a preparation method and application of the piezoelectric ceramic material, the piezoelectric ceramic material comprises lead tetraoxide, barium carbonate, niobium pentoxide, antimony trioxide, zirconium dioxide and titanium dioxide, the chemical formula of the piezoelectric ceramic material is (PbxBa1-x) 0.96 (Zr0. 42Ti0. 58) O3-(PbxBa1-x) 0.04 (Sb0. 5Nb0. 5) O3, and x is equal to 0.88-0.96. The lead tetraoxide, the barium carbonate, the niobium pentoxide, the antimony trioxide, the zirconium dioxide and the titanium dioxide are adopted to form the piezoelectric ceramic material under a certain mole number, so that the piezoelectric ceramic material not only has a relatively high piezoelectric coefficient, but also can keep relatively high stability in a relatively wide temperature range, and is high in measurement result accuracy and good in stability. The sensor can be used in an ultrasonic gas meter.
本发明属于压电材料技术领域，涉及一种温度适应范围宽的压电陶瓷材料、传感器及其制备方法和应用，压电陶瓷材料包括四氧化三铅、碳酸钡、五氧化二铌、三氧化二锑、二氧化锆和二氧化钛，压电陶瓷材料的化学式为：(PbxBa1‑x)0.96(Zr0.42Ti0.58)O3‑(PbxBa1‑x)0.04(Sb0.5Nb0.5)O3，x＝0.88～0.96。本发明采用四氧化三铅、碳酸钡、五氧化二铌、三氧化二锑、二氧化锆和二氧化钛在一定的摩尔数下形成一种压电陶瓷材料，不仅具有较高的压电系数，还能在较宽的温度范围内保持较高的稳定性，测量结果精准度高，能作为传感器用于超声波燃气表中。
