Shaping method of laminated piezoelectric ceramic piece
The invention discloses a shaping method of a laminated piezoelectric ceramic piece, which belongs to the technical field of piezoelectric ceramics and is mainly completed by a burning bearing plate,an aluminum oxide gasket, a laminated piezoelectric ceramic piece to be shaped, an aluminum oxide piece and the like. According to the shaping method, the buckling deformation piece is shaped in a secondary sintering mode after load bearing, load bearing shaping is that an aluminum oxide gasket with good flatness is used for clamping a piece to be shaped to achieve the leveling effect, the load weight is calculated according to the size and thickness of the laminated piezoelectric ceramic piece, and the shaping temperature is lower than the primary sintering temperature by 5%-10%. According tothe shaping method, the ceramic wafer subjected to buckling deformation after one-time sintering can be shaped until the flatness meets the use requirement, and in addition, the shaping temperature is far lower than the one-time sintering temperature, so that the product performance cannot be influenced.
本发明公开了一种叠层压电陶瓷片的整形方法，属于压电陶瓷技术领域，主要是通过承烧板、氧化铝垫片、待整形叠层压电陶瓷片、氧化铝片等共同完成。该整形方法是通过负重后二次烧结方式对翘曲变形片子进行整形，负重整形是使用平整度好的氧化铝垫片将待整形片子夹住起到整平作用，负载重量根据叠层压电陶瓷片尺寸、厚度进行计算，整形温度低于一次烧结温度5%‑10%。依照此整形方法，可将一次烧结后发生翘曲变形陶瓷片整形至平整度符合使用要求，另外，由于整形温度远低于一次烧结温度，不会对产品性能造成影响。
