| Abstract: | The empirical formula, -( T-T 02 )( T-T 01 ) A 2=d 1d 2A 1 ,is derived from complementary formula used for adjusting dielectric constant and displacement formula derived by vibration model of B-site ions,and the characteristics of ferroelectric PZN and PMN based ceramic materials under biased voltage were studied. It is found that the change of effective dielectric constant under biased voltage is related to structure of the materials, electric negative differences in A-site or B-site,the weighted average of electric negative differences and tolerant factors as well as amount of dopant. This formula is very effective for adjusting the dielectric constant of ferroelectric ceramics of PZN/PT and PMN/PZN/PT systems under biased voltage. |
