Structural, electrical and piezoelectric properties of nanocrystalline tin-substituted barium titanate ceramics

“…Barium titanate BaTiO 3 (BT) is one of the most widely studied lead-free ferroelectric ceramics due to its excellent properties, high dielectric constant [1,2] and low loss characteristics [3]. At the Curie temperature of 120 • C, the crystal structure of BT changes from tetragonal to cubic accompanied by a sharp peak in the relative permittivity.…”

Relaxor behavior in (Ba1−3/2Bi )(Zr Ti1−)O3 ceramics

“…In particular, there is a renewed interest in the environmental friendly lead-free perovskite Ba(Zr y Ti 1Ày )O 3 (BZT) as a substitute for Ba 1Àx Sr x TiO 3 (BST) in these applications due to its high dielectric constant value combined with relatively low dissipation and large voltage tunability of the dielectric constant, as well as a good chemical stability [4][5][6]. Depending on the Zr content, this material can exhibit either a normal ferroelectric or relaxor www.elsevier.com/locate/ceramint behavior [7][8][9][10][11][12][13].…”

Electrical and Physical Characterization of Bulk Ceramics and Thick Layers of Barium Titanate Manufactured Using Nanopowders

“…In these techniques, typical layer thicknesses range from 0.1 lm to a few lm ( Ref 7,8). When for thicker layers are desired (>10 lm) the preceding methods are no longer used; instead, dip coating, spin coating, and chemical vapor deposition techniques with limited success for thick coating are used.…”
