GENERAL DESCRIPTION & APPLICATIONS
Ultramarine is a blue pigment consisting of sodium aluminosilicate with three sulphur atoms in a form of sulfide or sulfate in which unpaired S3- anion originates the blue color. It is prepared by heating kaolin, sodium carbonate, sulfur and other inexpensive modifier ingredients. Synthetic ultramarine does not show vivid blue as much as natural ultramarine due to even particle size which diffuses light more evenly. Synthetic ultramarine color is affected by light, oil, or lime. Ultramarine features heat and alkali resistance. It is used as a colorant and optical whitening agent for plastics, rubber, inks, paints, cosmetics, detergents, cement, textile and paper.
