Varied hues of color in line with many specifications, fine bright red powder though in a variety of specifications.
Better dispersion. Strong covering power and tinctorial strength, a specific gravity of about 5.1, and average particle size < 1 micron. Small water absorption, good penetrability for ultraviolet ray, more stable in the atmosphere and under the sunlight, good light-fastness, heat and good alkali resistance, only soluble in the hot strong acid.

Addition compound of ferrous oxide and ferric oxide, with magnetism, high strength and covering power, good resistance to light and atmosphere, good light-fastness, and no impermeability or oil residue. It is very stable in general organic solvents, not resistant to acid, soluble in hot strong acid. Good alkali resistance
