This product is produced as by-products on Pickling line at steel works, which is the process that the scales are de-scaled from the surface of cold rolled iron sheet.
Iron oxide has been used for iron oxide pigments for a long time and it became to be used for manufacturing ferrite cores since 1940s. We can supply high purity iron oxides (purity >99.4) for soft ferrites by removing impurities, and calcine with MnO, etc. These products are Mn-Zn, Mg-Zn ferrite. The product for manufacturing iron oxide pigment has ferric oxide content more than 85%. |
