red/yellow/green/black/orange/blue/brown iron oxide pigments prices
Iron oxide are widespread in nature, play an important role in many geological and biological processes, and are widely used by humans, e.g., as pigment, catalysts, in thermite (see the diagram) and hemoglobin. Common rust is a form of iron(III) oxide. Iron oxides are widely used as inexpensive, durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range.
