Synthesis of high-purity nanocrystalline BiFeO3

The kinetics of BiFeO 3 formation from xerogel prepared by reverse coprecipitation were studied at different synthesis temperatures. We examined the influence of annealing temperature on the morphology of the reaction products and optimized synthesis conditions, which allowed us to obtain 99.7 wt %...

Zusammenfassung:The kinetics of BiFeO 3 formation from xerogel prepared by reverse coprecipitation were studied at different synthesis temperatures. We examined the influence of annealing temperature on the morphology of the reaction products and optimized synthesis conditions, which allowed us to obtain 99.7 wt % pure BiFeO 3 consisting of crystalline grains less than 50 nm in size. Its magnetic properties were investigated.
