Abstract: The present invention pertains to a method for producing a colloidal suspension of zirconia particles, comprising the following successive steps: a) subjecting a mixture of zirconium oxychloride and an alkali metal halide in an aqueous solvent to hydrothermal treatment at a temperature above 150° C., so as to obtain a suspension in the form of a two-phase mixture comprising a slurry and a supernatant, b) without first peptizing it, desalting said suspension so as to form a colloidal suspension of zirconia.

Abstract: Process for the preparation of a polysiloxane resin composition for antiabrasive coating of high refractive index, characterised in that it comprises the hydrolysis of a first constituent of organosiloxane type to an alkoxysilane hydrolysate containing condensable silanol groups, and the reaction of the hydrolysate obtained with a second constituent consisting of an organic titanium compound containing at least one carboxylic acid titanic ester functional group, with addition of a quantity of water suitable to cause the hydrolysis of the remaining hydrolysable groups in the mixture obtained and the formation of a siloxane prepolymer incorporating the titanium.
