“…By adding ZrO 2 into BaTiO 3 , the core-shell structure developed and does not exhibit exaggerated grain growth. It can be shown from the SEM images that the ZrO 2 modified BZT ceramics exhibit fine grain size and tetragonal structure to cubic structural transformation [16][17][18][19]. Figure 4a and b shows the frequency dependence of the dielectric constant and tan δ of Ba(Ti 1−x Zr x )O 3 ceramics (x = 0 ÷ 0.3) measured at 1 kHz to 1 MHz.…”

Ba(Ti1−xZrx)O3 (x = 0 ÷ 0.3) ceramics were prepared by the standard solid state reaction method and were sintered at 1450• C for 4 h. The structural and dielectric properties of the samples were studied. The phases formed in the ZrO2 doped BaTiO3 were tetragonal and of cubic symmetry. Increase in ZrO2 content in the BaTiO3 caused to increase of the lattice parameter and crystallite size of the perovskite structure. The evolution of the Raman spectra was studied for various compositions and the spectroscopic signature of the corresponding phase was determined. The scanning electron microscope was used to investigate the microstructure and surface morphology of the sintered samples. Scanning electron microscope observations revealed enhanced microstructural uniformity and retarded grain growth with increase of ZrO2 content. Dielectric characteristics of ZrO2 doped barium titanate were studied using a Hioki 3532-50 LCR meter in the frequency range of 1 kHz-1 MHz. It is found that the dielectric constant (εr) increases while the dielectric loss (tan δ) decreases with increase in zirconium oxide content (x < 0.3).

“…Veliki broj radova posvećen je uticaju mikrostrukture na dielektrične osobine barijum titanatnih keramika [86,87,[244][245][246]. Mikrostruktura sinterovane keramike zavisi od karakteristika polaznog praha i uslova sinterovanja.…”

“…Burfoot [246] su predložili sledeću empirijsku jednačinu (2.6) za temperatursku varijaciju (za temperaturski opseg iznad Curi-eve temperature) ε r tokom faznog prelaza od normalnog feroelektričnog (λ fazni prelaz) do difuznog faznog prelaza: Da bi se poboljšao kontakt između elektroda od srebra i površina uzoraka, obe baze uzoraka su premazivane suspenzijom praha srebra i etil acetata.…”

“…Martirena i Burfoot [246] su predložili empirijsku relaciju (2.6) da opišu temperatursku promenu ε r tokom faznog prelaza od normalnog feroelektričnog (λ fazni prelaz) do difuznog faznog prelaza (relacija 2.6 važi u temperaturskom intervalu iznad Curie-ve temperature). Ovakva razlika između paraelektričnog i feroelektročnog stanja implicira da unutrašnje naprezanje ima značajnu ulogu u efektu veličine zrna, zato što unutrašnje naprezanje ne postoji u kubičnoj fazi ali se razvija kada se BT keramika ohladi ispod T c [244] Za sadržaj kalaja manji od 10 mol%, BTS keramike pokazuju konvencionalne feroelektrične karakteristike sa dva fazna prelaza (1) kubična-tetragonalna faza T c i (2) tetragonalna-ortorombična faza T 1 .…”
