Below 912 °C (1,674 °F), iron has a body-centered cubic (bcc) crystal structure and is known as α-iron or ferrite.It is thermodynamically stable and a fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-Fe discussed below.
The calcium aluminoferrite phase acts as a repository for many of the minor elements in the clinker. Most of the transition metals in the cement are found in the ferrite phase, notably titanium, manganese and zinc. There is also a substantial amount of magnesium and silicon, and because of this, oxides other than CaO, Al 2 O 3 and Fe 2 O
A ferrite bead – also called a ferrite block, ferrite core, ferrite ring, EMI filter, or ferrite choke [1] [2] – is a type of choke that suppresses high-frequency electronic noise in electronic circuits. Ferrite beads employ high-frequency current dissipation in a ferrite ceramic to build high-frequency noise suppression devices.
Other names include "loopstick antenna", "ferrod", and "ferrite-rod antenna". "Ferroceptor" [7] is an older alternative name for a ferrite rod aerial, mainly used by Philips where the ferrite core would be called a "Ferroxcube" rod (a brand name acquired by Yageo from Philips in the year 2000). The short terms "ferrite rod" or "loop-stick ...
The ferrite magnets are mainly low-cost magnets since they are made from cheap raw materials: iron oxide and Ba- or Sr-carbonate. However, a new low cost magnet, Mn–Al alloy, [ 36 ] [ non-primary source needed ] [ 42 ] [ 43 ] has been developed and is now dominating the low-cost magnets field.
