Definition of ferrite in English: ferritenoun ˈfɛrʌɪtˈfɛraɪt mass noun1A ceramic compound consisting of a mixed oxide of iron and one or more other metals which has ferrimagnetic properties and is used in high-frequency electrical components such as aerials. Example sentencesExamples - Product groups include passive and electromechanical components, capacitors, resistive products, ferrites, fuses, inductors and filters.
- The remainder enters into solid solution in the ferrite with the non-carbide forming elements nickel and silicon.
- He said that in this approach the core can be a highly magnetic material like iron or iron alloys, while the shell can be a mixed metal ferrite with tailored resistivity.
- Some of the physical incidents in haunts, including interference with electrical equipment and movement of objects with ferrite components, may also be due to anomalous electromagnetic conditions.
- Neodymium magnets have dropped the weight by half of conventional ferrite car speakers and in the aftermarket have gained acceptance.
2Metallurgy A form of pure iron with a body-centred cubic crystal structure, occurring in low-carbon steel. Example sentencesExamples - The microstructure is thus converted to ferrite, and the excess carbon is deposited on the existing nodules.
- Trip steels have a microstructure with retained austenite, ferrite and martensite.
- The refinement of the grain size of ferrite provides one of the most important strengthening routes in the heal treatment of steels.
- The solubility of both C and N in austenite should be greater than in ferrite, because of the larger interstices available.
- They exhibit an austenitic matrix, although several grades also contain some ferrite.
