Description

Deliverable goal is to create improved Strontium Ferrite Powder based on an increase in coercivity and limited remanence loss with no use of critical raw materials (e.g. lanthanum and cobalt, as it is the case for high-quality commercial Sr-ferrite). Two strategies were therefore taken into consideration: ferrite powder for compounding/injection molding and for sintering, similarly to previous work reported in D1.3. The production process involves mixing of raw materials (iron oxide, strontium carbonate and additives) with water to form a slurry, which is then pumped in the high temperature ovens. The powder is then cooled, transported to the milling equipment and delivered to other PASSENGER partners for further characterisations and testing. Table 1 summarises the deliverable goals and the achieved values for the two applications.
