Iron hydroxide oxide Usage And Synthesis

Chemical Properties

reddish-brown crystalline solid

Uses

In purifying water; as absorbent in chemical processing; as pigment; as catalyst.

Uses

Iron(III) hydroxide, γ-phase is used in purifying water and as an absorbent in chemical processes. It is involved in the preparation of iron oxide-hydroxides nanoparticles, which is used as a very good adsorbent for lead removal from aquatic media. It is also used as a pigment, as a catalyst and in aquarium water treatment as a phosphate binder. Further, it is employed in the paints-lacquers-varnishes industry.

General Description

contains varying amounts of MgO₂, SiO₂, CaO, Al₂O₃
