Electro-caloric effects in the BaTiO3-based solid solution ceramics

Autor: Chae Il Cheon, Bit Chan Kim

Publikováno v: Journal of the Korean Ceramic Society. 57:578-584

Electro-caloric effect (ECE) was investigated in BaTiO3 (BT)-based solid solution ceramics, Ba(Zr,Ti)O3 (BZT), Ba(Sn,Ti)O3 (BST) and (Ba,Ca)(Zr,Ti)O3 (BCZT) with the composition near an invariant critical point (ICP). The samples were fabricated by t

Effect of Sintering Temperature on the Ferroelectric Properties and the Electro-caloric Effect in Barium-Titanate Ceramics

Autor: Chae Il Cheon, Bit Chan Kim, Ki Woong Chae

Publikováno v: Journal of the Korean Physical Society. 76:226-230

BaTiO3 ceramics were fabricated at various sintering temperatures by using a conventional solid-oxide reaction method. The ferroelectric properties and the electro-caloric effect (ECE) were investigated as functions of the sintering temperature. The

Publikováno v: Journal of Applied Physics. 126:234101

The electrocaloric effect (ECE) in lead-free (Bi0.5Na0.5)TiO3-SrTiO3 (BNT-ST) ceramics was investigated by direct and indirect measurements. Polarization-electric field hysteresis loops of the BNT-ST ceramics changed from well-saturated shapes at roo
