Webferrite, a ceramic-like material with magnetic properties that are useful in many types of electronic devices. Ferrites are hard, brittle, iron-containing, and generally gray or black and are polycrystalline— i.e., made up of a large number of small crystals. They are composed of iron oxide and one or more other metals in chemical combination.
