Magnetic core and method for manufacturing same

Claim 1

THE METHOD OF MANUFACTURING MAGNETIC CORES, COMPRISING THE STEPS OF SEPARATELY REACTING NI2O3, CO2O3 AND ZNO WITH FE2O3 IN THE RATIO OF ONE EQUIVALENT WEIGHT OF THE NICKEL AND COBALT OXIDES TO ABOUT TWO EQUIVALENT WEIGHTS OF IRON OXIDE AND ONE MOLECULAR WEIGHT OF ZINC OXIDE TO ONE MOLECULAR EQUIVALENT IRON OXIDE AT A TEMPERATURE WITHIN THE RANGE OF 2000-2500* F. FOR FROM 1-4 HOURS, COMPOUNDING THE REACTION PRODUCTS IN FINELY DIVIDED FORM WITH VANADIUM OXIDE AND MAGNESIUM ZIRCONATE AND A BINDER IN AMOUNTS RANGING UP TO 8 PERCENT OF THE MIX, MOLDING THE MIX TO MOLD SHAPE, HEAT TREATING THE MOLDED MASS AT A TEMPERATURE WITHIN THE RANGE OF 18002200* F. FOR 1/2-2 HOURS, AND THEN SLOWLY COOLING THE HEAT TREATED MASS TO ROOM CONDITIONS, THE MATERIALS BEING INCORPORATED IN AMOUNTS RANGING FROM 8-12 PARTS COBALT OXIDE, 6-12 PARTS NICKEL OXIDE, 5-15 PARTS ZINC OXIDE, 1-10 PARTS VANADIUM OXIDE, 4-12 PARTS MAGNESIUM ZIRCONATE, AND 40-65 PARTS IRON OXIDE.
