Yellow Oxide
Yellow oxides are chemical compounds composed of iron and oxygen. Several iron oxides are recognized. All are black magnetic solids. Often they are non-stoichiometric. Oxyhydroxides are a related class of compounds, perhaps the best known of which is rust.
Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes. Colors commonly available are in the “earthy” end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172.
Application
“Yellow oxide is a highly concentrated dry powder of the finest grade and is ideally suited
for use in paints, rubber, paper, polishing rouge, ceramic, linoleum, wall paper, plastic asphalt,
cement colours, mosaic tiles and flooring. It is also plays a role in foundry core making and
ferrite, which is used by the electronic industries.”
