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. 

A few other ceramic nanoparticles have been studied to date for orthopedic applications, most of which, however, are used as additives to other orthopedic materials. For example, bare or functionahzed magnesium oxide, zirconia, barium sulfate, and calcium carbonate are added to polymethylmethacrylate (PMMA) bone cement to reduce the exothermic effect of PMMA while increase its cytocompatibility. X-ray radiopac-ity, as well as antibacterial potential [65],...
