PROPERTIES OF LANTHANUM DOPED BARIUM TITANATE PRODUCED FROM NANOPOWDERS
(4'n Workshop Fabrication, Properties & Applications of Electroceramic Nanostructures, Abstracts June 26-28,2008 Genoa, Italy, 2008)
As a first discovered ferroelectric ceramic, barium titanate has become one of the
most extensively investigated ceramic materials used in electronics. For many years, A- and
B-site dopants have been used to modify the ...
EFFECT OF POWDER SYNTHESIS ON CRYSTAL AND MICROSTRUCTURE OF BaTiO3
(COST Action 539 - ELENA 2'd Workshop, Brussels, November 15-16, 2006, 2006)
Barium titanate (BaTiO3) has been used in many applications such as multilayer
capacitors, piezoelectric ceramics, transducer devices, PTC resistor and has become one of
the most important ferroelectric ceramics. It is ...
CHARACTERIZATION OF BARIUM BISMUTH TITANATE PREPARED BY MECHANICAL ASSISTED SYNTHESIS
(COST Action 539 - ELENA 4'th Workshop, Genoa, June 26-28, 2008, 2008)
Barium bismuth titanate (BaBi4Ti4O15 - BBiT) is an n=4 member of the Bi-base-layer-
structure ferroelectric oxide family (Aurivillius phase). A lot of aspects of the
preparation and properties of BBiTremain unexplored, ...
Arrival times and biometric correlation in Sylviine warblers in Vojvodina, Serbia
(Journal of OrnithologySpringer, 2006)
Five of the 17 western Palearctic warblers of the genus Sylvia occur in Vojvodina, the northern province of Serbia. Of these, only two, the Blackcap (S. atricapilla) and Greater Whitethroat
(S. communis), are common, ...
Sezonska horizontalna distribucija i abundancija vrsta familija Temoridae u Bokokotorskom zalivu

U Bokokotorskom zalivu registrovane su dvije vrste Copepoda iz familije Temoridae: Temora stylifera (Dana, 1849) i Temora longicornis (Müller 1792). U radu dajemo podatke o horizontalnoj distribuciji i abundanciji ovih ...
Microstructure and Dielectric Properties of Lanthanum Doped Barium Titanate
(6th Workshop COST 539, 23-25. February 2009, Madrid, Spain, Programme and book of abstracts, p 64-65, 2009)
Barium titanate has a special place in the group of ferroelectric perovskites because it can be formulated in a large number of systems and solid solutions that provide a wide range of various applications. The perovskite ...
DIELECTRIC INVESTIGATION OF BARIUM TITANATE WITH 0.5% ANTIMONY
(6th Workshop COST 539, 23-25. February 2009, Madrid, Spain, Programme and book of abstracts, p 64-65, 2009)
Barium titanate (BaTiO:) is versatile electroceramic that exhibits high permittivity
(e') making it desirable material for capacitor and others widespread applications. On
heating, it undergoes a ferroelectric/paraelectric ...
DIELECTRIC INVESTIGATIONS OF BARIUM TITANATE DOPED WITH DEFERENT CONCENTRATION OF LANTHANUM OR ANTIMONY
