noun
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.
‘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.’
- ‘The remainder enters into solid solution in the ferrite with the non-carbide forming elements nickel and silicon.’
- ‘Product groups include passive and electromechanical components, capacitors, resistive products, ferrites, fuses, inductors and filters.’
- ‘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.‘Trip steels have a microstructure with retained austenite, ferrite and martensite.’- ‘The microstructure is thus converted to ferrite, and the excess carbon is deposited on the existing nodules.’
- ‘They exhibit an austenitic matrix, although several grades also contain some ferrite.’
- ‘The solubility of both C and N in austenite should be greater than in ferrite, because of the larger interstices available.’
- ‘The refinement of the grain size of ferrite provides one of the most important strengthening routes in the heal treatment of steels.’
Origin
Mid 19th century from Latin ferrum ‘iron’ + -ite.
