Ferrite Ball Milling Fe Powder
ferrite ball milling fe powder . The initial ferrite powders composed of Fe 2O 3, Mn 2O 3 and MnZnFe 2O 4 oxides were charged with stainless ball into jars in high energy ball milling equipment. The ball milling was conducted with the ball to powder weight ratio of 20:1 and the milling rate of 300 rpm for 3 h under argon atmosphere. (PDF) Structural and Magnetic Properties of. Structural and
