In all kinds of pigments, iron oxide green pigment production and sales after thetitanium dioxide is the inorganic pigments, second large volume is large, the first color pigment. Iron oxide pigment color, chromatography wide, high covering power, tinting strength, the main colors are red, yellow, black three, composite pigment can also beorange, brown, green, by adjusting the series of chromatography. Iron oxide pigmentshave very good light fastness, weather resistance, acid resistance, alkali resistanceand solvent resistance, but also has the characteristics of innocuity, widely used in building materials, paint, printing ink, plastics, ceramics, paper, magnetic recordingmaterials etc..

The by-product ferrous sulfate of titanium white as the raw material, iron oxideproducts can produce many kinds of, is the best way to deal with ferrous sulfate.

The production of iron oxide red 1.1. calcination method

Iron grade American market sales of about 80, a total of about 20 is calcinedcopperas red iron oxide production; Japanese calcination method the largest in the world, with an annual output of about 200000 tons, but the product is mainly used as magnetic materials. Our factories in Zibo cobalt industry mainly by calcination ofproduction, but the product quality is low, not widely used, tin a nitrate method is widely used in quality and domestic far.

The current global iron oxide pigment, 60% for building materials, 30% for coatings.These two kinds of uses of iron oxide are required to have good color and dispersion,coloring power for iron oxide building materials must also have a higher (tinting strength low will make the pigment content increased, effects of material strength and other properties.). Copperas calcination production of iron oxide particles is larger,darker and tinting strength is not high, basically can not be used in building materials,the scope of application which makes them greatly reduced.
