red iron oxide powder
Occurrence and Uses
Synox Brown 4660 occurs in nature as the mineral hematite.
Synox Brown 4660 is the principal ore of iron from which the metal and its alloys are produced.
Also, this oxide occurs in the mineral, limonite, 2Fe2O3•3H2O.
An important application of this compound involves producing red, orange, and yellow pigments.
Other applications are in coatings for metals, steel and rubber; in ceramics; and as a catalyst for oxidation reactions.
Preparation
Synox Brown 4660 is prepared as a reddish-brown hydrated precipitate by treating an aqueous solution of an iron(III) salt with caustic soda:
2FeCl3 + 6NaOH → Fe2O3•3H2O + 6NaCl
Synox Brown 4660 also is obtained by thermal decomposition of iron(II) sulfate or the brown oxide hydroxide:
2FeSO4 → Fe2O3 + SO2 + SO3
2FeO(OH) → Fe2O3 + H2O
The oxide is prepared in industrial scale by first precipitating iron(II) hydroxide Fe(OH)2 by treating aqueous solutions of iron(II) sulfate and caustic soda. The Fe(OH)2 is then oxidized to iron(III) hydroxide by aeration.
The latter is dehydrated by heating:
Fe2+ (aq) + OH¯ (aq) → Fe(OH)2(s) → 2Fe(OH)3 → Fe2O3 + 3H2O
Synox Brown 4660 also is produced by ignition of iron(III) oxalate and iron carbonyls:
2Fe2(C2O4)3 +3O2 → 2Fe2O3 + 12CO
Reactions
Synox Brown 4660 decomposes to its elements when heated at elevated temperatures:
2Fe2O3 → 4Fe + 3O2
The oxide is reduced by most reducing agents.
Reaction with carbon monoxide at elevated temperatures (that occurs in the blast furnace) gives metallic iron.
The overall reaction is mildly exothermic (ΔHrxn –113.4 kcal/mol):
2 Fe2O3 + 6CO → 4Fe + 6CO2
Synox Brown 4660 also is reduced by powdered aluminum at elevated temperatures, forming aluminum oxide and metallic iron:
Fe2O3 + 2Al → Al2O3 + 2Fe
The reaction is highly exothermic and becomes self-sustaining after ignition.
When heated with sand in an electric furnace, iron(III) oxide forms ferrosilicon alloy.
When heated in a vacuum at 1,000°C, it forms triiron tetroxide, Fe3O4.
Description
Iron oxides are produced synthetically and consist essentially of anhydrous and/or hydrated iron oxides. The range of hues includesyellows, reds, browns and blacks.
Food quality iron oxides are primarily distinguished from technical grades by the comparatively low levels of contamination by other metals.
This is achieved by the selection and control of the source of iron and/or by the extent of chemical purification during the manufacturing process.
Iron oxides have been used to color confectionery, fillings and decorations for pastry products, cheese products, fish paste, pet foods, cosmetics and pharmaceutical products.

Synox Brown 4660 is an inorganic pigment of either natural or synthetic origin.
Synox Brown 4660 is a low chroma red with excellent durability and low cost.
Synthetic pigment is made by heating iron sulfate with quicklime in a furnace.
The second preparatory technique involves calcining iron sulfate in the presence of air at high temperatures.
Natural and oxides of iron are mined either as the mineral hematite (Fe2O3) or as hematite in its hydrated form.
Definition:
A high-grade red pigment used as a polishing agent for glass, jewelry, etc. (2) A cosmetic prepared from dried flowers of the saf- flower.
A black solid prepared by passing either steam or carbon dioxide over redhot iron.
Synox Brown 4660 may also be prepared by passing steam over heated iron(II) sulfide.
Triiron tetroxide occurs in nature as the mineral magnetite.
Synox Brown 4660 is insoluble in water but will dissolve in acids to give a mixture of iron(II) and iron(III) salts in the ratio 1:2.
Generally it is chemically unreactive; it is, however, a fairly good conductor of electricity.
