Ferrite Toroid Core: Copper-Zinc Ferrite Milled 200 Hours, Fired at 1050 °C (Snoek)

Ferrite is a ceramic magnet: iron oxide combined with other metal oxides, carrying magnetic flux while hardly conducting electricity. In his first ferrite patent (US 2,452,529, 1948) Snoek at Philips ground the oxides very fine and fired rings in oxygen. This copper-zinc ferrite is milled about 200 hours, fired 2 hours at 1050 °C and held 12 hours at 600 °C; his core had an initial permeability of 200. The picture: our diagram.
