Abstract研究了Nd~(3+)离子A位置换改性(Pb_(0.5)Ca_(0.5))(Fe_(0.5)Nb_(0.5))O_3陶瓷的微波介电性能。[P_b_(0.5)Ca_(0.5)_(1-x)Nd_x](Fe_(0.5)Nb_(0.5)O_3(PCNFN)陶瓷的微波介电性能得到改善是由于少量过剩的Nd~(3+)与(Pb,Ca)~(2+)的固溶能够消除氧空位。当x=0.02时,能够形成单相的钙钛矿相,随着Nd~(3+)置换量的增加,过剩的Nd~(3+)将导致第二相焦绿石的形成,焦绿石会恶化PCNFN的微波介电性能。P

Other AbstractMicrowave dielectric properties of A-site substitution by Nd3+ in (Pb0.5Ca0.5)(Fe-0.5 Nb-0.5)O-3 system were investigated. Microwave dielectric properties of [(Pb0.5Ca0.5)(1-x)Nd-x](Fe-0.5 Nb-0.5)O-3 (PCNFN) were improved because the solid solution of small amount of surplus Nd3+ with (Pb,Ca)(2+) could eliminate oxygen vacancies. A single perovskite phase was formed when x = 0.02. Surplus Nd3+ resulted in the formation of secondary phase (pyrochlore), which can deteriorate to the microwave dielectric properties of PCNFN ceramics. The decreasing of dielectric properties with x content was mainly caused by the formation of pyrochlore. Dielectric constant was above 100 and quality factor Qf values were 5385similar to5797GHz as x = 0.02similar to0.05. Temperature coefficient of resonant frequency (TCF) was changed from positive to negative with the increase of x content.
