Iron Oxide

CAS NO.: 1332-37-2

EINECS NO.: 215-570-8

Iron Oxide is the second largest inorganic pigment after Titanium Dioxide and the first largest color inorganic pigment. Iron oxide pigments mainly refer to Iron Oxide Red, iron yellow, iron black and iron brown pigments with iron oxide as the basic material. Iron oxide red is the main pigment (accounting for about 50% of iron oxide pigments). Mica iron oxide used as antirust pigment and magnetic iron oxide used as magnetic recording material also belong to the category of iron oxide pigments.

In the building materials industry, iron oxide is mainly used for color cement, color cement floor tiles, color cement tiles, imitation glazed tiles, concrete floor tiles, color mortar, color asphalt, terrazzo, mosaic tiles, artificial marble and wall painting; Used for coloring and protecting various coatings, including water-based interior and exterior wall coatings, powder coatings, etc; It can also be applied to oily paints, including epoxy, alkyd, amino and other primers and topcoats; It can also be used for toy paint, decorative paint, furniture paint, electrophoretic paint and enamel. Iron red primer has anti rust function and can replace high priced red lead paint to save non-ferrous metals.
Used for coloring plastic products, such as thermosetting plastics and thermoplastics, and coloring rubber products, such as automobile inner tube, aircraft inner tube, bicycle inner tube, etc. It is used for high-grade fine grinding materials and polishing precision hardware instruments, optical glass, etc. High purity is the main base material of powder metallurgy, which is used to smelt various magnetic alloys and other high-grade alloy steels. It is obtained by calcining ferrous sulfate or Iron Oxide Yellow or lower foot iron at high temperature, or directly from liquid medium.
