Why ferrites are used in high-frequency applications?
The ferrites are crystals having small electric conductivity compared to ferromagnetic materials. Thus they are useful in high-frequency devices because of the absence of significant eddy current losses.
What are the application of ferrites?
Ferrites are used in thermal sensing switches used in refrigerators, air conditioners, electronic ovens, etc. The magnetostrictive property of ferrites is utilized in producing ultrasonic waves from a ferrite rod by the application of an alternating magnetic field.
What are ferrites and their applications explain all the different types of ferrites?
Ferrite is a magnetic material of two types one is soft ferrite and second is the hard ferrite. Soft ferrite is class of magnetic material used as transformer core mainly for television, telecommunication computer, medical and other industrial electronic system.
What is the formula of ferrite?
Cobalt ferrite with the chemical formula CoFe2O4 (CoO·Fe2O3) is in between both soft and hard magnetic material and can be usually classified as a semi-hard material.
What are the properties of ferrite?
A strong magnetic property, relatively low conductivity, low eddy current and dielectric losses, and high permeability are the important properties of ferrite materials.
What types of material are ferrites?
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.
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 is the symbol for ferrite?
A low-temperature phase of iron, stable up to 911ºC, which has a body-centred cubic crystal structure and is commonly denoted by the Greek letter alpha (α). Ferrite is the magnetic form of iron. Ferrite is unable to absorb any significant amount of carbon – about 0.01% maximum.
What is called ferrite?
A ferrite is a type of ceramic compound composed of iron oxide (Fe2O3) combined chemically with one or more additional metallic elements. They are ferrimagnetic, meaning they can be magnetized or attracted to a magnet, and are electrically nonconductive, one of the few substances that combine these two properties.
What is ferrite made of?
Barium ferrite is also known by two chemical symbols BaFe12O19 or BaO. 6Fe2O3. Ferrite Magnets (Ceramic Magnets) are produced by calcining (at between 1000 to 1350 degrees C) a mixture of iron oxide (Fe2O3) and strontium carbonate (SrCO3) or barium carbonate (BaCO3) to form a metallic oxide.
