Bond valence structure analysis of doped bismuth sodium titanate [PDF]
14th IEEE International Symposium on Applications of Ferroelectrics, 2004. ISAF-04. 2004, 2005 This study focuses on a lead free, high temperature ceramic capacitor material having the base composition of (Bi/sub 0.5/Na/sub 0.5/)TiO/sub 3/. The goal is to modify this structure to create a material that has X7R-like dielectric behavior, while maintaining its inherently good high temperature dielectric properties.
