<p>A method for synthesizing TiO<SUB>2</SUB>, metal-doped TiO<SUB>2</SUB>, and metal-coated TiO<SUB>2</SUB> particles of spherical form factor and needle type of which the average particle size is below 150nm. The method of the invention is to synthesize Ti(OH)<SUB>4</SUB>, metal-doped Ti(OH)4 or metal-coated Ti(OH)4, and react the same by applying a pressure above the saturated vapor pressure at a temperature above 100°C. The pressure is achieved by means of the pressure of the vapor generated during the reaction inside of a closed reactor, by pressure applied from the outside, or a mixture of both. Gases to increase the pressure from outside are preferably inert gases such as Ar and N<SUB>2</SUB> but are not limited to inert gases.</p> |
