It was produced for the first time in 1847. The pigment grew more widely in the 20th century.

It has optimal granulometry, high whiteness and hiding power and anticorrosive effects. It is used as a pigment in the paint industry, in the manufacture of rubber, paper, plastic, ceramic, cement and sealing compounds.
