摘要

Preparation of the substituted barium ferrite BaFe_12-2x(CoTi)_xO₁₉ ultrafine particles by stearic acid gel method were investigated. The average particle size, structure and magnetic properties were measured. At 650 °C the well crystallized BaFe_12-2x (CoTi)_xO₁₄ ultrafine particles as small as 10 nm were also obtained. The magnetic properties vary with calcining temperature and grain size. The best magnetic properties have been obtained for the products calcined around 900 °C.
