TiO<inf>2</inf> as white pigment and valorization of the waste coming from its production
Abstract:
Titanium dioxide pigment, also called “titanium white” (or Pigment White 6), is an essential element in many manufacturing processes with minerals of significant economic importance: ilmenite, rutile, and anatase. Approximately 95% of titanium is consumed in the form of titanium dioxide (TiO2), a white pigment used for coating, paper, printing ink, paint, plastic, food, and, in addition, pharmaceutical, cosmetic, and textile industries. TiO2 pigment is characterized by its purity, refractive index, particle size, and surface properties, and its use as white pigment is due mainly to its high refractive index. Titanium dioxide pigments are manufactured by two routes: (1) the sulfate process (about 40% of total TiO2 production) and (2) the chloride process (about 60%). Valorization of the waste generated from industrial processes is an important area of the circular economy and, for that reason, the valorization studies of the wastes and coproducts generated will be analyzed.
