Magnetic Hematite



An artificially created magnetic material (this contains NO natural Hematite) widely sold as 'magnetic hematite' or simply 'hematite'. Please note that the name 'hematite' is quite misleading, as this is NOT a natural stone.

Investigation of one item offered for sale as 'magnetic hematite' showed it was composed of a ceramic barium-strontium ferrite magnet: (Ba,Sr)Fe12O19 that has the magnetoplumbite structure. The average grain size of the ceramic is 5-10 microns, and the porosity is 10-15%. In addition, the magnetic field strength of this material is much larger than that of any magnetite specimen.
Other items were identified as magnetoplumbite-type SrFe12O19.
