ABSTRACT:
Titanium dioxide nanoparticles are formed using a dispersing agent to form nanoparticles with desired size, shape, and uniformity. The titanium dioxide nanoparticles are formed by reacting an inorganic titanium compound with water or ice to form an aqueous titanium compound. The aqueous titanium compound is reacted or combined with a dispersing agent. Titanium dioxide nanoparticles are precipitated to form a suspension. The formation of the titanium dioxide nanoparticles is influenced by the presence of bonding of the dispersing agent. The size of the nanoparticles can be advantageously controlled by selecting the ratio of titanium to dispersing agent. In addition, the titanium dioxide nanoparticles can be used in suspension form or filtered and dried to form a powder.
