Paper Title:
Modification of Ba6-3xSm8+2xTi18O54 (x=2/3)Microwave Dielectric Ceramics by Nd/Bi Co-Substitution on A-Site
  Abstract

Ba6-3xSm8+2xTi18O54 microwave dielectric ceramics were modified by Nd/Bi co-substitution for Sm on A-site. According to XRD and SEM analysis, a single-phase solid solution with new tungsten bronze-type structure was formed in low-Bi-substituted region. Bi was effective on increasing dielectric constant, while led to a decreased Qf value and an increased negative tf. The co-substituting approach exhibited the advantage in improving e and compensating Qf and tf value.
