The subject of the invention is a glass-, ceramic-vitroceramic based substrate () provided on at least part of at least one of its faces with a coating () with a photocatalytic property containing at least partially crystalline titanium oxide. It also relates to the applications of such a substrate and to its method of preparation.

Substrate with a photocatalytic coating

The present invention provides a process for a producing a coating float-glass substrate, comprising chemical vapor depositing at least one titanium precursor on at least part of at least one face of a float-glass substrate produced in a float-bath chamber, to produce a photocatalytic coating containing at least partially crystalline titanium oxide.

The subject of the invention is glazing which incorporates at least one electrically controllable system having variable optical and/or energy properties, especially in the form of a system comprising one or more reversible-insertion materials of the electrochromic-system type, in the form of an optical-valve or viologen-based system or in the form of a liquid-crystal or cholesteric-gel system. This glazing also includes at least one means for adjusting the optical appearance conferred on the said glazing by the said system, these means comprising at least one coating having antireflection properties in the visible.

Glazing with optical and/or energetic properties capable of being electrically controlled

The subject of the invention is a glass-, ceramic- or vitroceramic-based substrate () provided on at least part of at least one of its faces with a coating () with a photocatalytic property containing at least partially crystalline titanium oxide. It also relates to the applications of such a substrate and to its method of preparation.

Method for depositing a reflective layer on glass, and products obtained

A metal nitride or oxynitride layer is pyrolytically deposited onto a transparent substrate by a process consisting of simultaneously bringing into contact at least one metal precursor and at least one amine as a nitrogen precursor into contact with said substrate which is heated for a high temperature.
