Abstract

Visokotemperaturna reakcija Bi2O3 i Fe2O3 se obavlja na temperaturama iznad 1023В°K kada, pri produženom mlevenju, dolazi do delimične razgradnje novostvorenog jedinjenja usled otparavanja Bi2O3. Produženim mlevenjem polazne smeše dolazi do pojave BiFeO3 (2-3 %) već na sobnoj temperaturi. Značajno povišenje sadržaja BiFeO3 počinje na temperaturama iznad 873В°K. Kompletno formiranje BiFeO3 (> 95 %) se ostvaruje do 973В°K čime je onemogućena razgradnja novostvorenog jedinjenja.Iz praha koji je podvrgnut produženom mlevenju dobijeni su uzorci BiFeO3 sinterovani na temperaturama do 973В°K sa povišenim specifičnim električnim otporom što je povoljno sa stanovišta ispitivanja feroelektričnih osobina materijala i njihovog korišćenja kao feroelektrika.The high temperature reaction of Bi2O3 and Fe2O3 is carried out at temperatures above 1023V ° K when, upon prolonged milling, partial degradation of the newly formed compound occurs due to the evaporation of Bi2O3. Prolonged grinding of the starting mixture results in the appearance of BiFeO3 (2-3%) already at room temperature. A significant increase in BiFeO3 content begins at temperatures above 873V ° K. The complete formation of BiFeO3 (> 95%) is achieved up to 973V ° K, which prevents the degradation of the newly formed compound. ferroelectric properties of materials and their use as ferroelectrics.
