    Abstract: The significant effects of sintering atmosphere and setter materials on the zinc loss of Mn-Zn ferrites are shown. It is demonstrated that the zinc loss will reduce the initial permeability from 11000 to 6000. The key sintering parameters increasing this zinc loss are low oxygen atmosphere in high temperature, high gas flow rate in the furnace, and the reaction of zinc oxide with Al

  • Understanding Zinc Penetration on Induction

    Zinc is commonly included in ferrous scrap used to charge induction-melting furnaces for foundries, but zinc also affects the refractory lining material, requiring some changes to the sintering procedure — in order to maintain the lining's effectiveness. For example, it helps to charge the zinc-coated steel scrap early in the melt cycle, allowing more time for the zinc to evaporate out of

    The sintering process takes place in furnaces that cool materials at a rate consistent with the creation of martensitic, crystalline structures. At first, discrete particles remain because complete compaction or melting does not occur. In powder metallurgy, the selected sintering temperature is always lower than the melting point of the primary metal in the material. However, the selected
