Multiferroic BiFeO3 ceramics were synthesized by chemical co-precipitation. The effects of calcination temperature and time on crystal structure, morphology and grain size of products were investigated. Ions of Ba and Ti were doped to modify the properties of BiFeO3 ceramics for improving ferroelectric and ferromagnetic properties. It is found that compared to the products before doping, the products with Ba doping at an amount of 30% in mass fraction can have the saturation magnetization enhanced from 4.69 emu/g to 4.93 emu/g; while the products with Ti doping at 10% in mass fraction can have the remnant magnetization enhanced from 0.047 emu/g to 0.164 emu/g. The co-doped ceramic samples combine the effects of A-site and B-site doping and exhibit enhanced multiferroic properties.
