Relaxor ferroelectric single crystals, such as pb ( mg1 / 3nb2 / 3 ) - pbtio3 ( abbreviated as pmnt ) or pb ( zn1 / 3nb2 / 3 ) - pbtio3 ( abbreviated as pznt ), have been reported to exhibit an extremely large piezoelectric constant and excellent electrostrictive properties. such excellent performance makes it fully substitute the traditional piezoelectric ceramics and points to a revolution in ultrasonic transducers, actuators and micro - positioners, making relaxor - based piezocrystals the most promising materials for a broad range of advanced applications. however, it is difficult to grow the high quality single crystals because of the lack of valid thermodynamic data
新型弛豫鐵電單晶鈮鎂酸鉛(簡稱pmnt )或鈮鋅酸鉛(簡稱pznt )是一類新興的功能材料,其在準同型相界附近具有優于傳統壓電陶瓷的較高的壓電常數和電致伸縮系數,可完全代替傳統的壓電陶瓷作為超聲換能器、致動器、微位移器等,使其成為鐵電領域的研究熱點,但如何生長出滿足應用要求的單晶材料卻一直是一個困擾的問題。Discussion on technology of field shaping for plumbum block and multilobate collimator
