Iron Oxide Red Inorganic Pigment .
Color is steel or silver gray to black in some forms and red to brown in earthy forms. Sometimes tarnished with irredescent colors when in a hydrated form (called Turgite).
Luster is metallic or dull in earthy and oolitic forms.
Transparency: Crystals are opaque.
Crystal System is trigonal; bar 3 2/m
Crystal Habits include tabular crystals of varying thickness sometimes twinned, micaceous (specular), botryoidal and massive. also earthy or oolitic.
Cleavage is absent however there is a parting on two planes.
Fracture is uneven.
Hardness is 5 - 6
Specific Gravity is 5.3 (slightly above average for metallic minerals)
Streak is blood red to brownish red for earthy forms.
Properties: it is powder with several colours, such as red, brown, black, yellow, blue. It is stable, insoluble in water while soluble in hydrochloric acid and dilute sulphuric acid.
Application: Iron Oxide pigment is mostly used in automotive paints and wood finishes. Meanwhile it is also widely used in the areas of architectural paints, industrial coatings, plastic, nylon, rubber, printing ink, art coatings, cosmetics and powder coating.
Purity(fe2o3):80.0% min
Moisture:0.30%max
Water soluble salt:0.50%max
Residue(45um):0.3%max
Tinting strength:95-105%
Ph of aqueous extract: 6.5-8.5
Volatiles at 105ípc:1.0%max .
5. Properties: red to reddish brown powder. Odorless. Insoluble in water, organic acids and organic solvents. Soluble in inorganic acids. There are ±-type (positive magnetic) and ³-type (diamagnetic) two types. The products produced by the dry method generally have a fineness of less than 1 m. Stable to light, heat and air. It is stable to acid and alkali. Strong tinting strength.
6. Uses: used in magnetic materials, polishing and abrasive materials, coatings and ink industries, etc.
Seven, packaging: lined with polyethylene plastic bags, outer plastic woven bags, 25Kg per bag.
8. Storage and transportation: It should be stored in a dry, ventilated and clean warehouse, lightly packed to prevent moisture and heat, and rain and moisture during transportation
5. Properties: insoluble in water, alkaline solution and organic solvents such as ethanol and ether. Natural ferric oxide is insoluble in acid solution, and is easily oxidized to iron oxide (Fe2O3) in the air in a humid state.
6. Uses: used as pigments and polishing agents, and can also be used in the manufacture of audio tapes and telecommunication equipment.
Seven, packaging: lined with polyethylene plastic bags, outer plastic woven bags, 25Kg per bag.
8. Storage and transportation: It should be stored in a dry, ventilated and clean warehouse, lightly packed to prevent moisture and heat, and rain and moisture during transportation
