Sintering heating and cooling rates as a method of modifying electrical properties of BiFeO3 ceramics
Апстракт
Bismut ferrite powder was prepared by sol-gel method. It was calcined at 600 °C and then milled
in order to break agglomerates and eventually obtain ceramic samples of high density. Such way
treated powders were pressed uniaxially under 196 MPa and sintered at 800 °C. Conventionaly
sintered samples were heated by the rate of 10 °C/min and furnace cooled. Other samples were
inserted into preheated oven and/or taken out from the hot oven directly to air or water at room
temperature. Influence of heating and cooling rates on structure, microstructure and electrical
properties were studied. Reducing the processing time in temperature interval between 447 °C and
767 °C prevents formation of secondary phases, but the effect on phase composition is not large. It
is significantly easier to notice the effect on electrical properties.
