Titanium dioxide particles, process for the production of titanium dioxide particles and use of titanium dioxide particles

摘要

The invention relates to microporous titanium dioxide particles and a method for the production of titanium dioxide particles. The titanium dioxide particles according to the invention are characterized by a density of less than 1.9 g / cm · 3 · and are by hydrolysis of hydrolyzable titanium compounds such as. B. Titanium tetraalkoxides obtained in non-polar dispersants. The process is characterized by mild conditions. With the method according to the invention, titanium dioxide particles with a particle size of 10 to 600 nm can be produced. DOLLAR A The titanium dioxide particles according to the invention can be used in particular as constituents in coating compositions, solar cells, batteries, foods, cosmetics or pharmaceuticals.
