Iron oxide yellow is an inorganic compound.
Iron oxide yellow is one of the three main types of iron oxide.
The other two are the rare Iron oxide yellow and the naturally occurring iron (II, III) oxide (Fe3O4), found in the mineral magnetite.
CAS: 12259-21-1
MF: Fe2H2O4
MW: 177.7
In the steel industry Iron oxide yellow is the primary source of iron.
In addition to being ferromagnetic, Iron oxide yellow is easily attacked by acids.
A precipitated pigment of finer particle size and greater tinctorial strength than the naturally occurring oxides such as ocher; excellent lightfastness and resistance to alkali.
Iron oxide yellow is one kind of oxides with stable chemical properties.
Iron oxide yellow is widely used in painting, scagliola and concrete due to its bright and pure color, good weather proof and high opacity, also can be used as colorant for ink, rubber, paper and so on.
Iron oxide yellow also known as Pigment yellow 42 is yellow powder in the form of an alkaline oxide with comparatively stable chemical properties.
Iron oxide yellow is slightly soluble in acids but completely dissolves in concentrated hydrochloric acid.
Iron oxide yellow is used in coating, printing ink and paint, and also as a coloring agent for building material, rubber and paper-making.
Iron oxide yellow widely used due to its bright and pure colour, good weather proofing and high opacity.
Iron oxide yellow is manufactured by the precipitation of ferric oxide hydroxide followed by purification through washing, drying and milling.
Iron oxide yellow are around 85% Fe2O3 and about 12% LOI with some impurities (e.g. SiO2, CaO).
In ceramics, Iron oxide yellow are used where its raw colour or other raw properties are important to the manufacturing process or colour of the unfired product.
Iron oxide yellow can produce yellowish honey colours (3%) but generally gives shades of brown (up to 8%) especially in lead glazes.
Iron oxide yellow has excellent hiding power, absorbs ultraviolet light, is compatible with a broad range of vehicles, disperses well in aqueous and solvent systems, does not contain heavy metals
Iron oxide yellow is a fine powdered pigment.
Iron oxide yellow is an insoluble pigment so it will need to be mixed with a small amount of light oil before adding to cold/hot process soap.
Mixing with isopropyl alcohol or liquid glycerine is recommended for melt and pour soap.
Less is more with oxides, if too much is used the colour can bleed and can also cause staining to washcloths and baths.
Over use can cause spotting in your soaps.
