摘要/Abstract

摘要： 作为一种主要的无铅压电陶瓷材料,Bi_(0.5)Na_(0.5)TiO_3(BNT)是一种优良的候选材料.以钛酸四丁酯、五水硝酸铋和无水乙酸钠为原料,用溶胶-凝胶法制备出清澈透明的BNT凝胶;BNT干凝胶经煅烧可得到BNT细粉.XRD谱线表明,其中主要含有杂相Bi_(12)TiO_(20).随着温度的升高,杂相的强度逐渐降低;同时,由于温度的升高,BNT粉体的晶粒增大.XRD指标化后的结果表明,BNT粉体的(101)晶面的原子排列的有序度较好.

Abstract: Bismuth sodium titanate [Bi_(0.5)Na_(0.5)TiO_3, BNT] is considered to be an excellent candidate for a key material of lead-free piezoelectric ceramics. The clear and transparent gels of BNT can be prepared using tetrabutyl titanate, bismuth nitrate pentahydrate and sodium acetate anhydrous as starting materials by Sol-gel method, the BNT fine powders are produced after the dry gels are calcined. XRD patterns show that the second phase in BNT powders is Bi_(12)TiO_(20). With the temperature increasing, the intensity of the Bi_(12)TiO_(20) reduces and the grain size of BNT powders increases. Well-ordered atoms on (101) crystal plane of the powders are formed by characterization of XRD results.
