Strontium ferrite
SrFe12O19
Description
Hard magnetic materials, also commonly referred to as permanent magnets, have a high coercive force and are used in a wide variety of industrial applications, e.g. in electric motors. The annual consumption of hard magnetic materials is a multiple of soft magnetic materials.
Barium ferrite powders were largely substituted by strontium ferrite powder. The latter are pressed into ceramic magnets and sintered or bound in a plastic matrix in order to extrude, calender or process them by injection molding.
Quality
This is a black powder with a grain size of e.g. 1.6 - 3 microns (measured according to Fisher Sub Sieve Sizer - FSSS). The density is approx. 4.94 g / cm3.
The magnetic properties are measured, for example, as follows:
- Flux density / induction / remanence Br: 1350 - 1850 Gs (Gauss)
- Magnetization / Coercive Force HCi: 1100 - 2070 Oe (Oersted)
- Magn. Energy density BHmax. 0.62 - 0.73 MGOe
(all based on a calendered, plastic-bonded magnetic foil)
Other units of measurements are:
- Flux density Tesla / Millitesla (T / mT),
- Magnetization amperes per meter (a / m) as well as for the
- Energy density Joule per cubic meter (J / m3)
Packaging
Sacks, big bags or in the silo vehicle
Storage
Store in closed containers, dry and ventilated rooms for a long time.
