C8 Ceramic Magnets Disc Magnet
In general you'll discover magnets made from iron or alloy, even though they can be created out of copper or other metals too.
Magnets have tremendous applications in our everyday lives and in numerous industries. Magnets found in nature are called lodestones.
Ceramic Magnets are extremely powerful and brittle, requiring appropriate handling and packing to guarantee safety and protect against damage. They are very resistant to corrosion. They are manufactured using powder technology techniques.
Ferrite is a kind of ferromagnetic metal oxide. In terms of electrical properties, the resistivity of ferrite is much larger than that of metal and alloy magnetic materials, and it has higher dielectric properties. Ferrite magnetic energy also shows high permeability at high frequencies. As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current. Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetization and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
Ferrite belongs to the category of semiconductor in electricity, so it is also called magnetic semiconductor. Magnetite (mainly Fe3O4) is the simplest form of ferrite. Ferrite has been synthesized in the world as early as the beginning of the 20th century. The Netherlands has been producing ferrite soft magnetic materials since 1946. China began industrial production of ferrite around 1956. Ferrite has been in radio communications, computing technology, automatic control, radar, navigation, space navigation, satellite communication, instrument measurement, printing, display, pollution treatment, biological medicine, high-speed transport a wide range of applications.
Ferrite is a compound oxide composed of iron and one or more other metals. Such as the chemical formula which best characterizes the spinel ferrite MeFe2O4 or MeO Fe2O3, of which the Me is ionic radius and the ferrous iron ion (Fe2 +) similar divalent metal ions (e.g. Mn2 +, Zn2 +, Cu2 + and Ni2 +, magnesium 2 +, Co2 +, etc.) or average group of chemical price of bivalent metal ions.
