Relaxor behaviour of BaBi4Ti4O15 ceramics
(Final Workshop COST 539, 28-30 October 2009, Aveiro, Portugal, Programme and book of extended abstracts, p 78-79, 2009)
Family of bismuth oxides was discovered more than 50 years ago by Aurivillius [1]. The lattice structure of the Aurivillius family of compounds is composed of n number of like perovskite (An-1BnO3n+3)2- unit cells sandwiched ...
INFRARED SPECTROSCOPY OF UNDOPED AND LA AND Sb DOPED BaTiO3 PREPARED BY POLYMERIC PRECURSORS METHOD
(Final Workshop COST 539, 28-30 October 2009, Aveiro, Portugal, Programme and book of extended abstracts, p 78-79, 2009)
The infrared spectra of ABO3 perovskites have been studied extensively. Factor
group analysis for BaTiO3 with cubic symmetry (space group Pm3m : O6r) predicts only
infrared bands (three triply degenerate infrared active ...
