Iron oxide red ( Fe2O3.αH2O ). It is the most stable compound in iron oxides. It has good heat resistance and does not change color at 500. The chemical structure does not change at 1200and is extremely stable. It can absorb the ultraviolet spectrum of sunlight, so it is protective for the coating. At meanwhile, it is has the character of Dilute acid resistance, alkali resistance, water resistance, and solvent resistance, so the iron oxide pigment has the good weather resistance. The particle size of iron oxide red was 0.2μm and with yellow phase, Surface area, oil absorption capacity is also large, as granularity increases, the hue moves from red to purple. As the particles getting larger, the relevant models for iron oxide red is 110, 101, 120, 130H, 130S, 130R , 130A , 190 and 180.
