【摘要】：采用低膨脹相材料、化學(xué)穩(wěn)定性強(qiáng)的基相材料及其它輔助相材料為主要原料,采用壓力注漿成型,自然干燥,常壓燒結(jié)工藝制備鉛基壓電陶瓷承燒板。研究晶相組成、顯微結(jié)構(gòu)對(duì)燒銀承燒板使用壽命的影響。結(jié)果表明:在最佳工藝條件下可制備熱膨脹系數(shù)α_((室溫~800℃))=2.81×10~(-6)℃~(-1),抗彎強(qiáng)度151.6 MPa,抗熱震性△T≥400℃不裂的陶瓷承燒器具,用作鉛基壓電陶瓷被銀后燒銀(700~850℃)承燒板,其使用壽命超過(guò)150次。
[Abstract]:Lead based piezoelectric ceramic sintered plate was prepared by pressure grouting, natural drying and sintering under normal pressure by using low expansion phase material, base phase material with strong chemical stability and other auxiliary phase materials as main raw materials. The effect of crystal phase composition and microstructure on the service life of silver bearing board was studied. The results show that the ceramic sintering apparatus with thermal expansion coefficient 偽 _ (room temperature ~ 800 鈩，
