Iron Oxide Pigments For Ceramic

Iron Oxide Pigments For Ceramic
Iron oxide red pigment is mainly introduced into ceramic pigment formula in the form of colorant. Such as brown series and black series in glaze pigment; zirconium iron oxide red pigment in zirconium series pigment; iron oxide red raw material is also widely used in black, coffee, brown series of billet pigment, as well as ceramic glazed tiles and other colorful cement bricks. Therefore, the dosage of iron oxide red pigment in ceramic pigment is very large, and the annual dosage is expected to be more than 10,000 tons. At present, the production methods of iron oxide red pigment used in ceramic pigment are mainly divided into sulfuric acid method and mixed acid method (nitric acid method). Take the thin iron plate as raw material, after processing, we get the red color bright iron oxide red pigment. Generally speaking, the comprehensive index of iron oxide red produced by nitric acid method is better than that of iron oxide red produced by sulfuric acid method.
