摘要：
Microwave dielectric properties of A-site substitution by Nd3+ in (Pb0.5Ca0.5)(Fe0.5Nb0.5)O-3 system were investigated. Microwave dielectric properties of [(Pb0.5Ca0.5)(1-x)Nd-x] (Fe0.5Nb0.5)O-3 (PCNFN) system with x = 0.02-0.05 were improved because the solid solution of small amount of excessive Nd3+ with (Pb,Ca)(2+) could eliminate oxygen vacancies. Surplus Nd3+ resulted in the formation of secondary phase (pyrochlore), which deteriorated the microwave dielectric properties of PCNFN ceramics. Dielectric constant was above 100 and quality factor Qf values were 5385-5797 GHz as x = 0.02-0.05. Temperature coefficient of resonant frequency (TCF) was changed from positive to negative with x content. (C) 2004 Elsevier B.V. All rights reserved.
