TROX

Tronox Holdings Plc

A maker of titanium dioxide, the white pigment that gives paints, plastics, paper, and inks their brightness and opacity, Tronox also mines the titanium-bearing mineral sands that feed its own plants. Born in 2005 as a spin-off from the oil-and-chemical firm Kerr-McGee, it grew into one of the world's largest producers after buying rival Cristal's titanium business in 2019. Its name blends "tron" (for titanium) and "ox" (for oxygen), the two elements that make its signature product.
