摘要:

 通过水热反应法低温烧结制备Ba0.85Ca0.15Zr0.1Ti0.9O3(BCZT)无铅压电陶瓷,研究了烧结温度和时间对BCZT陶瓷的晶体结构和电学性能的影响。与固相反应法相比,由于水热法制备的BCZT前驱体的高活性,可以低温烧结制备BCZT陶瓷,低温烧结制备的BCZT陶瓷呈现纯钙钛矿结构、较为均匀的小晶粒微观形貌(小于10 μm)和更高的致密度。通过水热法制备的BCZT陶瓷呈现优良的电学性能,其介电响应特征接近正常铁电体、又呈现一定的频率色散现象。1 340 ℃烧结18 h制备的BCZT陶瓷的剩余极化强度最大,Pr=6.84 μC/cm2。1 320 ℃烧结18 h制备的BCZT陶瓷压电性能最佳,d33达到最大值213 pC/N。
