1980-1-1 At 500 a transitional oxide is obtained which is charac- terized by magnetic attractability. Only trace amounts of hematite are converted to the transitional oxide. However, if the hematite had been drastically ground be- fore the preparation of the disks it was almost completely transformed into the transitional oxide.
