Use of rare earths in paints and pigments

Rare earths are used in the paints and pigments industry (i) as coating materials for pigments to enhance their durability and performance characteristics, (ii) in the manufacture of ceramic pigments and (iii) in the manufacture of driers for organic coatings. 

In solid solutions, rare earths impart colour to the solutions due to their electronic configurations. This property has been profitably used in the manufacture of ceramic pigments which are extensively used in colouring of wall and floor tiles, table-ware and sanitary-ware. Cerium and praseodymium are extensively used in ceramics pigments. The shades that result due to the use of cerium and praseodymium are yellow, orange and green.
