Barium sulfate (BaS04) has an industrial relevance due to its whiteness, inertness, high specific gravity, and optical properties, such as opacity to UV rays and X-rays [164-167]. It is mainly used as a radio-contrast agent, filler in plastics, extender in paints, coatings and additive in pharmaceutical products, and in printing ink. Nowadays, interest on this material has been renewed with the development of methods to produce nanosized particles, supraparticles of a well-controlled number of nanoparticles and mesocrystals that mimic biomineralization processes.
