Large transduction coefficient ($d_{33}\times g_{33}$) is difficult to obtain in piezoelectric ceramics because these two parameters show opposite trends with compositional modifications. Herein, the Pb(Zr_0.53Ti_0.47)O₃ ceramic powders were calcinated under different temperatures (A:830 °C, B:860 °C, and C:890 °C), and then mixed together according to different weight ratios (1A:1B:1C, 1A:2B:1C, 1A:2B:3C and 3A:2B:1C) for ceramics preparation. Both d₃₃ and g₃₃ are improved successfully, and the transduction coefficient with the weight ratio of 1A:2B:3C reaches up to 17,500 × 10⁻¹⁵ m²/N, which is 60 % higher than that with the powders calcinated under 830 °C, and at least twice those of commercial PZT-4, PZT-5A and PZT-8 ceramics. The improved transduction coefficient is owing to the enhanced piezoelectric constant and spontaneous polarization resulted from the increased grain size, relative density and the fraction of tetragonal phase. These results indicate that this is a simple but effective way to tailor the transduction coefficient in piezoelectric ceramics.

大转导系数（$d_{33}\times G_{33}$在压电陶瓷中很难获得，因为这两个参数显示出相反的趋势以及成分变化。本文中，将Pb（Zr _0.53 Ti _0.47）O ₃陶瓷粉末在不同温度（A：830°C，B：860°C和C：890°C）下煅烧，然后根据不同的重量比混合在一起（ 1A：1B：1C，1A：2B：1C，1A：2B：3C和3A：2B：1C）用于陶瓷制备。既d ₃₃和克₃₃被成功地提高，并且与图1A的重量比的传导系数：2B：3C达到高达17500×10 ^-15米²/ N，比在830°C下煅烧的粉末高出60％，至少是商业PZT-4，PZT-5A和PZT-8陶瓷的两倍。改进的转导系数归因于增强的压电常数和由于增加的晶粒尺寸，相对密度和四方相的分数而导致的自发极化。这些结果表明，这是一种简单而有效的方法，可以调整压电陶瓷的换能系数。
