Influence of the reagent types on the characteristics of …

 · As a result, single-phase barium hexaferrite powder BaFe 12 O 19 with an average particle size of about 200 nm and an average crystallite size of 46 nm was obtained. M-type barium hexaferrite powder synthesized using barium acetate as a reagent has high coercivity values ( H C = 334.2 kA/m), residual magnetization ( B r = 39.7 Am 2 /kg), and saturation magnetization ( M S = 73.9 Am 2 /kg).

Synthesis and magnetic properties of strontium hexaferrite …

 · Nanocrystalline strontium hexaferrite (SrFe 12 O 19) powders have been synthesized from Egyptian celestite ore (SrSO 4), as a source of strontium, via co-precipitation route. The raw celestite ore was first dissolved in hydrochloric acid to remove about 10% CaO and the acid soluble impurities associated with the ore.
