BAYFERROX RED 110 is a noncombustible, black to black red or brick-red mineral (iron ore) composed mainly of ferric oxide, Fe2O3.
Physical Properties
Reddish-brown hexagonal crystal; refractive index 2.91; density 5.25g/cm3; Moh’s hardness 6.0; melts at 1565°C; insoluble in water; dissolves in acids.
Uses
BAYFERROX RED 110 is a nutrient and dietary supplement that is a source of iron.
As pigment for rubber, paints, paper, linoleum, ceramics, glass; in paint for ironwork, ship hulls; as polishing agent for glass, precious metals, diamonds; in electrical resistors and semiconductors; in magnets, magnetic tapes; as catalyst; colloidal solutions as stain for polysaccharides.
BAYFERROX RED 110 is an inorganic pigment of either natural or synthetic origin.
BAYFERROX RED 110 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.
Reactions
BAYFERROX RED 110 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
BAYFERROX RED 110 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.
Preparation
BAYFERROX RED 110 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
BAYFERROX RED 110 also is obtained by thermal decomposition of iron(II) sulfate or the brown oxide hydroxide:
2FeSO4 → Fe2O3 + SO2 + SO3
2FeO(OH) → Fe2O3 + H2O
BAYFERROX RED 110 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
BAYFERROX RED 110It also is produced by ignition of iron(III) oxalate and iron carbonyls:
2Fe2(C2O4)3 +3O2 → 2Fe2O3 + 12CO
