Preparation method of compact lead zirconate titanate piezoelectric ceramic nanofiber
The invention relates to the field of piezoelectric ceramics, in particular to a preparation method of compact lead zirconate titanate piezoelectric ceramic nanofibers. The invention relates to a preparation method of compact lead zirconate titanate piezoelectric ceramic nanofibers. The preparation method is characterized by comprising the following steps: 1, preparing a lead zirconate titanate precursor solution; 2, electrostatic spinning; 3, performing sectional type high-temperature firing and crushing; the lead zirconate titanate piezoelectric ceramic nanofiber obtained through sectional type high-temperature firing is uniform, the surface is compact and free of holes, large gaps exist between the fibers, and the piezoelectric constant of the lead zirconate titanate piezoelectric ceramic nanofiber is increased and ranges from 550 pC/N to 580 pC/N.
本发明涉及压电陶瓷领域，尤其涉及一种致密型锆钛酸铅压电陶瓷纳米纤维的制备方法。一种致密型锆钛酸铅压电陶瓷纳米纤维的制备方法，其特征在于：包括步骤：1，制备锆钛酸铅前驱体溶液；2，静电纺丝；3，分段式高温烧制和破碎；采用分段式高温烧制得到的锆钛酸铅压电陶瓷纳米纤维均一且表面致密无孔洞，而且纤维之间存在较大空隙，提高了锆钛酸铅压电陶瓷纳米纤维的压电常数，压电常数为550～580pC/N。
