使用标准陶瓷方法合成了由 La3+ 取代 Bi3+ 和 (Ti4+,W6+) 取代 Nb5+ 形成的铁电 Bi3TiNbO9 固溶体。给出了作为替代函数的晶胞参数和介电性能的演变。所有化合物均表现出铁电相变，其温度随着取代率的增加而降低。讨论了晶体化学数据和介电行为之间的关系。
Solid solutions deriving from ferroelectric Bi3TiNbO9by cationic substitutions of La3+for Bi3+and (Ti4+,W6+) for Nb5+have been synthesized using a standard ceramic method. Evolutions of unit cell parameters and dielectric properties as a function of the substitution are given. All compounds show a ferroelectric phase transition, the temperature of which decreases with increasing substitution rate. The relations between the crystal chemical data and the dielectric behavior are discussed.
