The invention relates to a device () for mixing/dosing liquid coating materials, in particular for use in a coating system () for spectacle lenses, said device having at least a first and a second storage container (-) for liquid starting materials, a conveying device () for sucking in and expelling liquids, a mixing container (), and a liquid outlet () for mixed/dosed liquid coating materials. In between there is a multi-way valve (), which can be switched into different valve positions and is constructed to produce one of the following connections (a, b, c, d) and in the process to disconnect the other connections: (a) connection between the first storage container and the conveying device, (b) connection between the second storage container and the conveying device, (c) connection between the conveying device and the mixing container, and (d) connection between the conveying device and the liquid outlet.

A flame spray pyrolysis process for the preparation of ultrafine titania particles coated with a smooth, homogeneous coating of one or more metal oxides is provided. The metal oxide coating is achieved by contacting the titania particles with a metal oxide precursor downstream of the titania formation zone, after the titania particles have formed. The process provides titania particles with a high rutile content and a smooth and homogeneous coating of a metal oxide.
