Morphology of ferriferous glasses contained different percentage of hematite

The morphology of ferriferous glasses with different iron oxide (III) concentration: 15, 20 and 25% and two types of the magnetic porous glasses have been studied using atomic-force and transmission electron microscopy. The droplet iron bearing phase was detected both on the surface and in the volume of ferriferous glasses. The drops size and their density depended on the iron oxide concentration (Fe2O3).

The regions with different pore sizes and the effect of the partial etching of the iron bearing drops have been observed in porous magnetic matrices.
