What is Iron Oxide Yellow?

On an around the world scale, iron oxide is the 2nd biggest not natural pigment after titanium dioxide and the biggest tinted not natural pigment. Iron oxide pigments primarily consist of 4 categories of iron oxide red, yellow, black as well as brownish based upon iron oxides. Iron Oxide Yellow, furthermore referred to as iron oxyhydroxide (FeOOH), will absolutely dry and also decay and likewise redden at about 177 ° C, so the application of regular iron yellow pigments in heat applications such as plastic processing as well as baking layers is restricted. Iron Oxide Yellow pigment can enhance its temperature level resistance with surface area layer, subsequently increasing the application area of iron oxide yellow pigment.

The chemical formula of Iron Oxide Yellow (additionally known as hydroxy iron) is α-Fe2O3 · WATER or α-FeOOH.It is a needle-like structure as well as is a yellow powder with a particle dimension of less than 0.1 μm. It has good dispersibility in transparent media. The iron-based pigment has solid tinting toughness, high hiding power, insoluble in alkali, and a little soluble in acid. Synthetic Iron Oxide Yellow has the features of light resistance, good dispersibility, non-toxic, odor-free, and not easy to be taken in by the human body. It is commonly used in coverings, plastics, inks, as well as pharmaceutical sectors.

Iron Oxide Yellow Uses

1. Iron Oxide Yellow pigments are made use of as pigments or colorants for prefabricated parts and also structure products in numerous kinds of concrete, as well as are directly moved into cement for application. Numerous interior and also outside tinted concrete surface areas, such as walls, floors, ceilings, columns, verandas, sidewalks, parking lots, staircases, stations, etc; various architectural porcelains and also glazed ceramics, such as face floor tiles, floor tiles, roof covering tiles, panels, terrazzo, mosaic floor tiles, artificial marble, etc

2. Iron Oxide Yellow pigment is suitable for different paint coloring and also defense substances, including water-based interior and exterior wall surface coatings, powder finishes, and so on; additionally suitable for oil-based paints consisting of epoxy, alkyd, amino and other guides and also topcoats; additionally Can be used in plaything paints, ornamental paints, furniture paints, electrophoretic paints and also enamels.

3. Iron Oxide Yellow pigment is suitable for the coloring of plastic items, such as thermosetting plastics as well as thermoplastics, and also the coloring of rubber items, such as automobile internal tubes, aircraft internal tubes, bike internal tubes, etc

4.Commonly utilized in the coloring of made marble as well as likewise terrazzo in the structure and building market. It is a pigment for watercolor, oil paint, paint, rubber, etc. Made use of as an intermediate of iron oxide pigments, such as iron oxide red, iron black, and so forth.

Preparation of Iron Oxide Yellow

How to Make Iron Oxide Yellow

Technique 1: Ferrous sulfate oxidation technique
Sulfuric acid reacts with iron filings to create ferrous sulfate, sodium hydroxide is added as well as air is oxidized to prepare crystal cores, then ferrous sulfate as well as iron filings are added to the crystal core suspension, heated as well as blown into air for oxidation, as well as subjected to pressure filtration, washing, Dry as well as shatter to obtain yellow iron oxide. Its reaction equation is as follows:

Fe+ H2SO4 → FeSO4+ H2 ↑.

FeSO4 +2 NaOH → Fe( OH) 2+ Na2SO4.

4Fe( OH) 2+ O2 → 4FeOOH +2 WATER.

H2SO4+ Fe +7 H2O → FeSO4 · 7H2O+ H2 ↑. FeSO4 · 7H2O+ O2 → 2Fe2O3 · H2O ↓ +4 H2SO4 +2 WATER. Response problems: 74g of iron filings were contributed to 1000ml of 15% sulfuric acid to respond until the iron filings vanished to produce ferrous sulfate with a concentration of about 200g/L. Add enough 30% salt hydroxide to the ferrous sulfate option prepared over, stir continuously to convert 40% of the iron right into ferrous hydroxide [Fe( OH) 2], and ventilate at 30-35 ° C, to ensure that Fe is oxidized to Fe to develop crystal core. After that add 90g/L of iron filings to it to produce 7g/L of centers and also 40g/L of ferrous sulfate, continue to warm to 85 ° C, air-oxidize at a speed of 600L/h for 64h, after that filter, laundry, drying as well as crushing to acquire hydrated iron oxide yellow.

Method 2: Aromatic nitro compound oxidation approach Aromatic amino substances can be generated at the same time. Its response equation is as follows:.

Fe+ WATER+ R-NO2 → Fe2O3 · WATER+ R-NH2.

The reaction conditions are as complies with: 560 parts of water, 36.5 parts of 32% hydrochloric acid, 160 parts of iron powder and also 10 parts of light weight aluminum powder are included in the reaction pot. 1460 parts of a liquid service having 253 parts of 5-nitronaphthalenesulfonic acid and 8-nitronaphthalenesulfonic acid were included in the reaction pot for 16-24 hrs, the pH of the aqueous service of naphthalenesulfonic acid was 6, as well as the temperature level was 80-85 ° C. The temperature level in the reaction pot is 95 ~ 100 ℃, and also the pH value is 6 ~ 6.5. Under this problem, react for 2h, include 8 parts of 25% ammonia water, even more react for 4h, filter, clean the filter cake three times with 560 parts of water, and then filter the filter cake after cleaning with water. The cake is combined with 1000 parts of water, heated at 95-100 ° C, included with 45 parts of 32% hydrochloric acid, mixed for 2 hrs, filtered, washed with water till acid-free, dried to acquire 160 parts of iron oxide yellow pigment, as well as aminonaphthalenesulfonic acid can be obtained at the same time, the return is 96%.
