Abstract：MnZn ferrite powders were prepared by the chemical co-deposition method utilizing acid waste liquid in a iron plant and zinc slags as raw materials.The effects of reaction temperature on powders yield rate and particle size were studied.The feasibility of this technology applying to industrial produce was investigated.The morphology,crystalline structure and magnetic properties of reaction products were characterized.The result show that the positive spinel MnZn ferrite powders prepared have excellent crystallization behavior and good decentrality.The particle size range is are between 1 and 2 μm.The performance indexes of powders conform CL9F、CL10F powder standards in low flux density and closed iron core preparation range in the electronic industry standard of the People's Republic of China SJ/T 1766—1997.Considering the production efficiency in industrial production,the particle sizes are small and the yield rate of products is highest if control the reaction temperature between 45 and 50 ℃.
