摘要
Effects of V2O5 addition on the grain growth and magnetic properties of a high permeability manganese-zinc (Mn-Zn) ferrite were studied. The results showed that small additions Of V2O5 of < 0.03 wt% increased the permeability of Mn-Zn ferrites while higher amounts decreased it. The permeability of these samples showed pronounced secondary maxima in permeability versus V2O5 content. V2O5 UP to a certain percentage increased Curie temperature, saturation magnetic flux density and then decreased it, and also decreased specimen shrinkage noticeably. (c) 2006 Elsevier B.V.
