Titanium dioxide ( ${TiO}_{2}$ ) is a naturally occurring, white, opaque mineral that serves as a vital pigment across numerous industries due to its ability to provide brightness and opacity.1

In the manufacturing of paper, plastics, and inks, titanium dioxide is utilized primarily for its intense white color and high refractive index, which allows it to effectively mask underlying colors and provide a clean, bright finish.1

Regarding ceramics, titanium dioxide is employed as a bleaching and opacifying agent in porcelain enamels. Its inclusion in these materials enhances their aesthetic quality by providing brightness while simultaneously improving the physical properties of the finished product, specifically increasing its hardness and acid resistance.1
