33 )가 우수하여, 충격 센서, 가속도센서, 초음파 센서, 적층형 압전액추에이터, 압전변압기 및 초음파 진동자, 착화소자와 같은 고신뢰성 압전부품을 제조할 수 있으며, 납에 의한 환경 오염을 감소시킬 수 있는 이점이 있다.
The present invention relates to their preparation and non-lead piezoelectric ceramic composition, in a non-lead piezoelectric ceramic composition used as a sensor or actuator, to a non-lead piezoelectric ceramic for the raw material mixing, pulverization, drying, and sintering were prepared, respectively, paraelectric full phase and ferroelectric phase mixed and these awards are core-shell by producing the piezoelectric mold present in the structure, the domain on the ferroelectric in the phase change and the core region of the ferroelectric phase on the paraelectric full at the time the cell site electric field applied to the piezoelectric moldings and a non-lead piezoelectric ceramic compositions that are used as sensors or actuators, characterized in that indicating a high strain rate is a rearrangement occurs to a technical base. Thus the final piezoelectric molding while having the at least two more, the electric field is applied during phase change and the domain rearrangement occurs and the increase of the dielectric constant and piezoelectric constant due to the strain (d
33) is excellent, and shock sensors, acceleration sensors, ultrasound sensors, piezoelectric stack-type actuator, a piezoelectric transformer and an ultrasonic transducer, can be prepared a high-reliability piezoelectric component, such as the ignition device has the advantage of reducing the environmental contamination by lead.
