Abstract
Official abstract text for this publication.
A method of forming a titania-coated inorganic particle comprising the steps of (a) stirring a mixture of a titania precursor such as a titanium alkoxide and an inorganic particle such as a hollow glass particles in an organic solvent such as an alcohol for more than 1 h to cause adsorption of the titania precursor on the surface of the inorganic particle; and (b) adding water dropwise to the mixture under stirring to convert the titania precursor to titania which then forms a coating on the inorganic particle. A method for forming a paint formulation, a titania-coated inorganic particle, a paint formulation comprising a titania-coated inorganic particle and use of a titania-coated inorganic particle in a paint formulation is also described.
First claim
Opening claim text (preview).
What is claimed is: 1. A titania-coated inorganic particle, wherein said titania of the titania-coated inorganic particle is amorphous titania, and wherein said titania-coated inorganic particle has a density in the range of 0.1 g/mL to 1 g/mL. 2. The titania-coated inorganic particle of claim 1 , wherein said titania coating of the titania-coated inorganic particle is of a thickness in the range of 50 nm to 300 nm. 3. The titania-coating inorganic particle of claim 1 , wherein the titania coating is disposed on at least 90% of the surface of said inorganic particle.
