Iron oxide blue is mainly composed of magnetite, the chemical composition of which is Fe3O4, and the crystal belongs to the oxide of equiaxed crystal system. Iron blue has high coloring power, good light resistance, poor alkali resistance and high heat resistance. When the temperature exceeds 150 ℃, it loses crystal water and begins to decompose into red pigment. Uses: paint, ink, painting, pigment and crayon, paint cloth, paint paper, plastic products, building floors, floor tiles, etc.
