Iron Oxide Black Pigment Powder for Ceramic Concrete Bricks and Paints

High Tinting Strength The iron oxide red produced by the special production process, after being calcined at medium temperature, all the product particles are converted into a-Fe2O3, so that the red

High Hiding Power After iron oxide red is calcined at medium temperature, the particle size of the product is more uniform, and the hiding power is better, and the relative hiding power is greater th

Low Oil Absorption After the high-end calcination of iron oxide red, the surface of iron oxide red particles is denser, the oil absorption is lower, it is more conducive to dispersion and wetting, an

Low Impurity The first extraction method is used to prepare the reaction raw materials, the content of heavy metals is low, and the reaction is carried out in a closed space. The reaction process doe
