Improved dielectric properties in pyrochlore type oxides: Ca3Sm3−xBixTi7Nb2O26.5 (x = 1.0, 2.0 or 3.0) by Bi substitution

Prabhakar Rao, P; Ravindran Nair, K; Divya, P; Peter Koshy; Vaidyan, V K (Springer, 2005)

Improved dielectric properties are observed in pyrochlore type oxides, Ca3Sm3-x BixTi7Nb2O26.5 (x = 1.0, 2.0 or 3.0) by Bi substitution. The dielectric constant increased with increasing Bi concentration. The dielectric ...
New pyrochlore type semiconducting ceramic oxides: Ca3Ce3-xBixTi7Nb2O26.5(x=0.5, 1.0, 2.0, or 3.0) - structure, microstructure and electrical properties

Prabhakar Rao, P; Ravindran Nair, K; Seema, K V; Peter Koshy; Vaidyan, V K (Springer, 2005)

Oxides of the pyrochlore family have a general formula A2B2O7 and they have been extensively studied because of their wide spectrum of physical properties including electrical, magnetic, optical, dielectric, and catalytic ...
