RUTILE TITANIUM DIOXIDE MICROSPHERES AND ORDERED BOTRYOIDAL SHAPES OF SAME

摘要

Rutile TiO2 microspheres and microparticles in a botryoidal morphology which form from ordered acicular aggregates of elongated TiO2 crystallites that resemble nano-sized flower bouquets and/or triangular funnels, and process for their preparation by thermally hydrolyzing a soluble TiO2 precursor compound in aqueous solution in the presence of a morphology controlling agent selected from carboxylic acids and amino acids.
