Inorganic Pigments

Inorganic pigments are used to impart colors in different compounds. These pigments are made up of mineral compounds and these minerals are mainly oxides, sulphides of one or more than one metals.

Inorganic pigments can be obtained from various naturally occurring mineral sources or minerals which have been obtained synthetically.

• Inorganic pigments can withstand the impact of sunlight and chemical exposure in better way.
• They have good opacity and thus these can protect other objects by preventing the light.
• These pigments also increase rash inhibition, abrasion resistance and rigidity to the molecules.
• These pigments have more durability.
• These pigments are available at low cost in respect to the organic pigments.

These pigments have low tinting strength so a large number of pigments are required to produce the desired effects.

Color comes from inorganic pigments is comparatively less brighter. These pigments are also seemed to be less rich and pure than the organic pigments.

Inorganic pigments are available in various forms like: powder, pastes, slurries and suspensions.

The Inorganic Pigments are again divided into two sub types:

• Natural Inorganic Pigments
• Synthetic Inorganic Pigments
