METHOD FOR PRODUCING A MULTI-ELEMENT OXIDE MATERIAL CONTAINING THE ELEMENT IRON IN THE OXIDISED FORM

摘要

The invention relates to a method for producing a multi-element oxide material containing the element iron in the oxidised form, in which an aqueous iron nitrate solution is also used as a source of the elementary constituent iron. The invention also relates to the production of the melt of a solid hydrate of iron nitrate.
