Synthetic Iron Oxide Pigments
There are various process of manufacturing synthetic iron
oxide pigments. These methods are calcining, precipitation, reduction
thermal decomposition of iron compounds.
The common colors of these pigments are orange, red brown and yellow.
Basic chemicals are used for manufacturing of synthetic iron oxide pigments. To produce synthetic iron oxide pigments, iron salts or iron compounds are decomposed. By precipitating of iron salts and reducing the organic compounds by iron, pigments of synthetic iron oxide can be prepared.

These pigments are used in wood and paper stains,
linoleum, oilcloth, paints, mortar, plaster, bricks, rubber and for other
pigment able substances. The range of applications of synthetic Iron Oxide
Pigments is longer than the Natural Iron Oxide Pigments. But in few specific
cases, the uses of Natural Iron Oxide pigments can not be substituted by the
Synthetic iron Oxide Pigments.
Today, there is a lot of varieties of Synthetic Iron
Oxide Pigments are available in the market. These synthetic pigments are
found in different colors, having superior uniformity, excellent quality and
high purity. But, in reality, the Natural Iron Oxide Dyes are preferred over
theirs counterparts. This is because of theirs ample availability and low
cost of extraction.
The main difference between Synthetic and Natural Iron Oxide pigments is based on theirs purity. The Natural Iron Oxide Pigments contain contaminants that reduce the working efficiency of these pigments.
These contaminants can be divided into two types. One having of coloring property and second type of contaminant behave as extender. These contaminants with coloring property are often magnetite, MnO etc. while the non-coloring contaminants are often derived from the Natural pigments. These non-coloring contaminants are used in the industry as fillers, including talc, calcium carbonates and clays.
