Monodispersed micaceous iron oxide (MIO) pigment is prepared from pyrite cinders. SEM image (Fig. a, 11) reveals that the obtained MIO particles are uniform flakes, and their mean particle size is ~ 7.0 μm with an aspect ratio of ~ 7.0. XRD pattern (Fig. b) demonstrates that the synthesized MIO is well crystallized and coincides with hematite structure.

The iron atom has a strong magnetic moment due to four unpaired electrons in its 3d orbitals. When crystals are formed from iron atoms, different magnetic states can arise as shown in Fig. 2.In the paramagnetic state, the individual atomic magnetic moments are randomly aligned with respect to each other, and the crystal has a zero net magnetic moment.

MIO coatings are made with micaceous iron (MIO) pigment, a very dark coloured, layered mineral with a subtle metallic lustre. The flake-like shape of MIO pigments is the key to their protective powers. Like tiny mirrors, they reflect the UV light, protecting the underlying resin against chalking and creating the 'sparkle' appearance that ...
