Heavy iron oxide yellow and preparation method thereof

The invention relate to a heavy iron oxide yellow, which comprises high density iron oxide yellow powder. The high density iron oxide yellow powder is made from the iron oxide yellow powder with a ball mill through vibratory milling or milling. The bulk density of the heavy iron oxide yellow manufactured through milling method is increased by 10-70 percent compared with that of the general iron oxide yellow, therefore, the storage and transportation space occupied by the same amount of iron oxide yellow pigment is greatly reduced, and the transportation cost is lowered. The invention also has the advantages of simple technique and low cost.
