Lead-free ceramic and preparation method thereof, ceramic powder, piezoelectric ceramic and atomization device
The invention relates to lead-free ceramic and a preparation method thereof, ceramic powder, piezoelectric ceramic and an atomization device. The lead-free ceramic comprises a main component represented by a chemical formula (1-x) (KyNa1-y) (NbaSb0.97-aTa0.03) O3-x (BibNa1-bZrO3)-cMnO2, x, y, a and b respectively represent the number of particles, 0 < = x < 1, 0 < y < 1, 0 < a < = 0.97 and 0 < b < 1, c represents the mass percent of MnO2 in the main component, and 0 < = c < = 1%. The lead-free ceramic comprises a potassium sodium niobate phase with a specific proportion of a Ta element, and through the reasonable proportion of the lead-free ceramic composition, the piezoelectric property of the lead-free ceramic is relatively good, and the lead-free ceramic has relatively good piezoelectric constant, mechanical quality factor and electromechanical coupling coefficient.
本申请涉及一种无铅陶瓷及其制备方法、陶瓷粉体、压电陶瓷和雾化装置。该无铅陶瓷，包括以化学式(1‑x)(KyNa1‑y)(NbaSb0.97‑aTa0.03)O3‑x(BibNa1‑bZrO3)‑cMnO2表示的主体成分，其中，x、y、a和b分别表述粒子数，0≤x＜1，0＜y＜1，0＜a≤0.97，0＜b＜1，c代表MnO2在主体成分中的质量百分比，0≤c≤1％。该无铅陶瓷中包含特定比例Ta元素的铌酸钾钠相，通过无铅陶瓷组成的合理配比，无铅陶瓷的压电性能较好，兼具较佳的压电常数、机械品质因数和机电耦合系数。
