ABSTRACT:
A method of manufacturing a formed, ferromagnetic object, particularly an annular memory core, in which a quantity of ferrite powder, a ferrite sol and a polymerized, organic compound are mixed to form an aqueous solution, which is poured out in a thin layer. A solid, elastic gel is formed, from which rings can be punched, which, after sintering, can be used as cores for memories.
