roduct name: Iron Oxide Powder
Appearance :Red,yellow,black Green,Brown Blue Powder
Iron oxides are chemical compounds composed of iron and oxygen. widespread in nature, play an important role in many geological and biological processes, and are widely used by humans, e.g., as iron ores, pigments, catalysts, inthermite (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.
