body-centered cubic iron. Also, iron and steel alloys that have the BCC crystal structure.
The term "ferrite" is derived from the Latin word "ferrum", meaning iron. Ferrites are homogeneous ceramic materials composed of various oxides containing iron oxide as their main constituent. Ferrite has a cubic crystalline structure with the chemical formula MOÂ·Fe2O3 where Fe2O3 is iron oxide and MO refers to a combination of two or more divalent metal oxides such as zinc, nickel, manganese or copper. The addition of such metal oxides in various amounts allows the creation of many different materials whose properties can be tailored for a variety of uses. Being a ceramic material, ferrites are hard, inert, and free of organic substances. Ferrite is rigid and brittle. Like other ceramics, ferrite can easily chip and break if handled roughly. Often such chips and cracks are only cosmetic and do not affect the materials magnetic properties. Ferrite range in color from silver gray to black. The electromagnetic properties of ferrite materials can be affected by environmental and operating conditions such as temperature, pressure, field strength, frequency and time.
A solid solution in which alpha iron (body centered cubic crystal structure) is the solvent. In low carbon steel ferrite exists between room temperature and approximately 1330 F.
The room temperature form of alpha iron, one of the two major constituents of steel (cementite) in which it acts as the solvent to form solid solutions with such elements as manganese, nickel, silicon and, to a small degree, carbon.
(1) A solid solution of one or more elements in body-centered cubic iron. Unless otherwise designated (for instance, as chromium ferrite), the solute is generally assumed to be carbon. On some equilibrium diagrams, there are two ferrite regions separated by an austenite area. The lower area is alpha ferrite; the upper, delta ferrite. If there is no designation, alpha ferrite is assumed. (2) ln the held of magnetics, substances having the general formula: M2+O . M,23+O3, the trivalent metal often being iron.
A powdered, compressed and sintered magnetic material having high resistively. The high resistance makes eddy current losses low at high frequencies. Related Terms: ferrite bead
A composite material with excellent magnetic properties used to make isolators, circulators, and transformers.
Dense homogeneous ceramic structures made by mixing iron oxide (Fe203) with oxides or caronates of one or more metals such as manganese, zinc, nickel or magnesium. They are used in induction sealing systems to direct the electromagnetic field into a desired direction.
The body-centred cubic crystalline phase of iron-based alloys.
Ferrite is the name given any solid solution in which alpha iron is the solvent. Ferrite is strictly a structure name and means nothing as to composition.
This word comes from the Latin word for Iron; 'Ferrum'. First arriving in the 1950's, Ferrite magnets are very commonly used as they are cheap and easy to produce using mass manufacturing processes in a wide variety of shapes and sizes, and retain their magnetic properties for a very long time. They are ceramic in nature and are composed of around 80% ferric oxide (hematite, a form of Iron ore) and around 20% of either Barium oxide or Strontium oxide. (See also Demagnetizing).
The body-centered cubic crystalline phase of iron-based alloys.
A ceramic like chemical compound of iron oxide and either nickel-zinc, or manganese zinc oxide. The nickel-zinc, Ni-Zn, mixture has initial permeabilities ranging from 10 to 1,500 and are suitable for applications requiring low loss (high Q) at frequencies ranging from 1MHz to 250MHz. The Ni-Zn also displays a high resistivity factor typically on the order of 106 to 107 ohms/cm. Manganese-zinc, Mn-Zn, has permeabilities ranging from 2,000 to 15,000 and are usable over frequencies ranging from 400Hz to 1MHz. Mn-Zn materials have lower resistivity materials in the order of 101 to 102 ohms/cm. Normally these materials are used for power applications.
A constituent of carbon steels. It is magnetic and soft.
a ferromagnetic compound of ferric oxide used in the construction of magnetic recording heads and media
Iron practically carbon-free. It forms a body-centered-cubic-lattice and may hold in solution considerable amounts of silicon, nickel, or phosphorus; hence the term is also applied to solid solutions in which alpha or delta iron is the solvent.
Ferrites are electrically non-conductive ferrimagnetic ceramic compound materials, consisting of various mixtures of iron oxides such as Hematite (Fe2O3) or Magnetite (Fe3O4) and the oxides of other metals.
Ferrite or alpha iron (Î±-Fe) is a materials science term for iron, or a solid solution with iron as the main constituent, with a body centred cubic crystal structure. It is the component which gives steel and cast iron their magnetic properties, and is the classic example of a ferromagnetic material.
