(Ba1−xCax)(Ti1−yZry)O3 ceramics doped with various donors and acceptors were sintered in a reducing atmosphere and then annealed at different oxygen partial pressures. The dielectric maxima at the Curie point increased up to ∼30000 after reoxid

BaTiO3 and Ba(Ti,Zr)O3 dielectric powders have been prepared from submicrometer BaCO3, TiO2, and ZrO2. By use of submicrometer BaCO3 the intermediate formation of Ba2TiO4 second phase can be widely suppressed. Monophase perovskites of BaTiO3 were alr

Substitution of Dy rare earth ions was studied in Ba(Ti,Zr)O3 dielectric materials, using thermogravimetry, X-ray diffraction and dielectric measurements. Dy3+ ions enter both the A- and the B-sites of the perovskite structure, however, the solubilit

The dielectric properties of (Ba,Ca)(Ti,Zr)O3 ceramics containing various acceptor and donor dopants on the B sites have been studied. Formation of charge compensating “complexes” between acceptors, donors and oxygen vacancies has been observed.

Dielectric ceramics of the system (Ba,Ca)(Ti,Zr)O3 (BCTZ) have been fired with BaO-excess in reducive atmosphere. By the influence of BaO-excess the Ca2+-ions are shifted from the Ba- to the Ti-sites of the perovskite lattice. The solubility of Ca2+

Donor-doped BaTiO3 ceramics show very high endurance under DC field stress and are there-fore suitable candidates for the manufacture of multilayer capacitors with thin dielectric layers. CeO2 additives were found to be excellent donor dopants. The d

Clear, transparent gels of BaTi acetate have been prepared from titanium tetrabutylate (TBT), Ba acetate aqueous solution, isopropanol and acetic acid. Infrared spectroscopy and transmission electron microscopy (TEM) of such gels revealed linked clus
