摘      要：正BaFe12O19 has been applied as the vertical recording material, permanent magnetic material due to its large magnetic saturation, rectifying magnetic retentivity, crystal anisotropy and good chemical stability. In recent years, scientists have paid more attentions to study the way of preparing Ba-ferrite. Usually the chemical ceramic way was used to prepare Ba-ferrite, but it needs higher sintering temperature （1200℃）.
