Study on the Property of Bi2(Mg2/3Nb1.1833Sn0.15)O7 Dielectric Ceramics Doped With Li2CO3

摘要：

　　(Bi2-xLix) (Mg2/3Nb1.1833Sn0.15)O7 piezoelectric ceramics were prepared by conventional solid state reaction method.The microstructure and dielectric properties of dielectric ceramics were studied which was doped by different amount of Li2CO3.The experiment results showed that the density of the ceramics would decrease,but have little effect on the microstructure of the ceramics when the amount of the Li2CO3 doped increases.With the increasing of Li2CO3 doped,the dielectric constant(εr) and dielectric ioss(tanδ) of dielectric ceramics first decreases and then increases.When tested in 1 MHz frequency,the piezoelectric ceramics display the optimum properties tanδ is 0.00009,εr is 163 while Li2CO3 doped amount is 0.05 mol%.
