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.
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:
(all based on a calendered, plastic-bonded magnetic foil)
Other units of measurements are:
Sacks, big bags or in the silo vehicle
Store in closed containers, dry and ventilated rooms for a long time.
