Abstract: A METHOD FOR BONDING FERRITE COMPONENTS IN WHICH A GLASS BONDING MATERIAL IS CAUSED TO FILL THE GAP BETWEEN COMPONENTS. THE COMPONENTS AND GLAS ARE HEATED IN A CLOSED ENVIRONMENT AND THE PRESSURE IS REDUCED. AFTER OUTGASSING OF BUBBLES FROM THE GAP AND FERRITE HAS CEASED, THE PRESSURE IN THE ENVIRONMENT IS INCREASED, WHILE THE HEAT IS AT LEAST MAINTAINED, TO CAUSE THE GLASS TO FLOW INTO AND UNIFORMLY FILL THE GAP. THE GLASS, UPON HARDENING, THEN BONDS THE FERRITE COMPONENTS.
