【摘要】：采用熔鹽法制備了(Ba_(0.85)Ca_(0.15))(Zr_(0.1)Ti_(0.9))O_3(BCZT)無(wú)鉛壓電陶瓷。研究了熔鹽法制備的工藝參數(shù)包括預(yù)燒溫度和熔鹽比例。通過(guò)X線衍射(XRD)、電鏡掃描電子顯微鏡(SEM)等分析了不同工藝參數(shù)對(duì)該陶瓷物相結(jié)構(gòu)、微觀面貌和電學(xué)性能的影響。結(jié)果表明,在預(yù)燒溫度為900℃,反應(yīng)物與熔鹽的質(zhì)量比(熔鹽比)為1∶1時(shí),陶瓷樣品可獲得最佳綜合電學(xué)性能:剩余極化強(qiáng)度為10.8μC/cm~2,壓電常數(shù)為366pC/N。
[Abstract]:(Ba_ _ (0.85) Ca_ (0.15) (Zr_ _ (0.1) Ti_ _ (0.9) O _ (3) (BCZT) lead-free piezoelectric ceramics were prepared by molten salt method. The process parameters of molten salt preparation including pre-firing temperature and molten salt ratio were studied. The effects of different process parameters on the phase structure, microstructure and electrical properties of the ceramics were analyzed by means of X-ray diffraction (XRD),) electron microscope scanning electron microscope (SEM) and so on. The results show that when the pre-firing temperature is 900 鈩，
