| 摘 要： | 我们采用传统固态反应方法烧结制备(Nb2O5)1-x(TiO2)x陶瓷,给出了掺杂量x从0.01到0.13陶瓷的介电性能.在本工艺条件下,所有样品的介电系数均大于120.当样品中TiO2的掺杂量为5mol;时,陶瓷的介电性能最佳:介电系数和损耗分别为217和0.078.XRD测试实验给出,当x≤0.05时,陶瓷的主要相结构为Nb2O5;当x≥0.07时,主相为TiNb24O62.

| Abstract: | (Nb_2O_5)_(1-x)(TiO_2)_x ceramic system for x=0.01-0.13 were prepared by conventional solid-state reaction technique.All of the specimens showed high dielectric constants more than 120 with the process in this paper.The main phase structure is Nb_2O_5 when TiO_2 substitution is less than 5mol% or TiNb_(24)O_(62) while substitution more than 7mol% for the specimens by X-ray diffractions technique.The best dielectric properties were presented when TiO_2 substitution reaches 5mol%,dielectric constant and loss value of which are 217 and 0.078 respectively. |
