What are ferrites give examples?
Ferrites are usually ferrimagnetic ceramic compounds derived from iron oxides. Magnetite (Fe3O4) is a famous example. The magnetic material known as “ZnFe” has the formula ZnFe2O4, with Fe3+ occupying the octahedral sites and Zn2+ occupy the tetrahedral sites, it is an example of normal structure spinel ferrite.
What is called ferrite?
The ferret (Mustela furo) is a domestic species of small mustelid. The only domesticated species in Mustelidae, it is thought to be a descendant of the European polecat, a mammal belonging to the same genus as the weasel, Mustela.
What are ferrites and mention its types?
ferrite, 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.
What are the properties of ferrites?
A strong magnetic property, relatively low conductivity, low eddy current and dielectric losses, and high permeability are the important properties of ferrite materials.
What are ferrites and its classification?
Ferrites are classified according to magnetic properties and their crystal structure. Based on their magnetic properties, ferrites are often classified as “soft” and “hard” which refers to their low or high coercivity of their magnetism, respectively.
What are ferrites classification?
What are the different types of ferrites?
However, in most of the research work done on ferrites, scientists classify the ferrites according to their crystal structure. Hence technically speaking, there are four important classes of ferrites: (1) spinel ferrites, (2) garnet ferrites, (3) hexaferrites, and (4) ortho ferrites.
What are the common structures of ferrites?
Ferrites have variety of crystal structures. Based on their crystal structures, ferrites can be classified in four types, i.e., spinel, garnet, ortho, and hexagonal ferrites (Table 2).
What are ferrites properties?
The most important properties of ferrites include high magnetic permeability and high electrical resistance. High permeability to magnetic fields is particularly desirable in devices such as antennas. Ferrites of a type known as square-loop ferrites can be magnetized in either of two directions by an electric current.
