Iron oxide pigment is a kind of pigment with good dispersion, light and weather resistance. Iron oxide pigment mainly refers to iron oxide as basic material of iron oxide red, iron yellow, iron black and brown four kinds of pigments, which is given priority to with iron oxide red (about 50% of the iron oxide pigments), micaceous iron oxide used as antirust pigment, and used as a magnetic recording material of magnetic iron oxide also belongs to the category of iron oxide pigments. Iron oxide is the second largest inorganic pigment after titanium white and the largest color inorganic pigment. Of all the iron oxide pigments consumed, more than 70% are prepared by chemical synthesis method, which is called synthetic iron oxide. Synthetic iron oxide as the synthesis of high purity, uniform particle size, and the chromatography is extensive, color more, inexpensive, non-toxic, have excellent coloring and application performance, has the properties such as absorb ultraviolet light, and therefore is widely used in building materials, coatings, plastics, electronics, tobacco, medicine, rubber, ceramics and paper, ink, magnetic materials, etc, etc.   1. Good dispersion
2. Excellent light and weather resistance
3. Acid resistance
4. Water resistance
5. Solvent resistance
6. Resistance to other chemicals
7, alkali resistance
8, good coloration, no seepage, no migration
