| 采用傳統(tǒng)固相法制備(1-x)[0.95(Na0.5K0.5)NbO3-0.05LiNbO3]-xBiGaO3 (簡稱KNNL-BG-x)壓電陶瓷,研究鐵電化合物BiGaO3對KNNL-BG-x陶瓷的相結(jié)構(gòu)和電學(xué)性能的影響,用X射線衍射儀(XRD)和掃描電鏡(SEM)、壓電測量儀等,分析KNNL-BG-x無鉛壓電陶瓷的陶瓷的粒徑大小、表面形貌、壓電性能。結(jié)果表明:所有樣品都呈單一相的鈣鈦礦結(jié)構(gòu),沒有雜相,均為四方相結(jié)構(gòu),d33和kp的值都隨著x的增大先增大后減小,在x=0.005處獲得最大值:d33=280 pC/N,kp=49%,并且隨著x的增加能夠抑制晶粒的生長并且減小氧空洞,獲得質(zhì)密度高,晶粒均勻的產(chǎn)品 |

The (1-x)[0.95(Na0.5K0.5)NbO3-0.05LiNbO3]-xBiGaO3(KNNL-BG-x) piezoelectric ceramic was prepared based on traditional solid-state method. The effects of ferroelectric compounds to the phase structure and electrical performance of KNNL-BG-x were investigated , and the particle size, surface morphology and piezoelectric properties of KNNL-BG-x lead-free piezoelectric ceramics were analyzed by XRD, SEM and piezoelectric measurement machine in this paper. The results showed that all the samples possessed single phase perovskite structure with tetragonal phase structure and no impurity phase. The d33 and kp increased first and decreased afterwards with the increase of X. The maximum of d33 and kp (d33=280 pC/N,kp=49%) were obtained at x=0.005. The product with high mass density and uniform crystal grains was preparated due to that with the increase of X, grain growth was inhibited and the oxygen hole was decreased. |
