Treating Ferrite Cores

Ferrospinel cores are soaked in cyanide to enhance the rectangular hysteresis loop response-excitation characteristics.,

In treating ferrospinel cores such as manganese-magnesium ferrite material, green cores are first pre-heated to a temperature of 600 degrees C for a period of about four hours. The cores are then removed from the furnace, placed in a bath of sodium cyanide and soaked for about ten minutes. The cores are dried at room temperature and then resoaked in the sodium cyanide solution for a second brief period. Following this, the cores are fired, furnace cooled to a temperature slightly below the firing range, and then metal plate quenched to room temperature.

With this technique, the physical strength of the cores is increased and their temperature sensitivity decreased.
