The ferrite industries are expected to grow continuously and an estimated covering the market development of forthcoming years, in terms of produced annual tonnage, will be presented. The creation of uniform sintered structures, within the lower micron meter range, essentially free of duplex structures, is highly desireable for the production of a large proportion of soft and hard ferrite products. Several wet chemical processes have been proposed and are presently beeing carried out on a commercial scale for the production of ferrite powders. For the production of precisely controlled uncollapsed ferrite powders, exhibiting uniform primary particle sizes within the submicron meter range, should for cost savings, environmental and constant quality control purposes, be carried out at selected and integrated steel mills using short thermal sintering techniques. The advantage of an independent managemant - away from the core business stell - would be of mutual benefit to the ferrite and steel industries.
