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

Process according to one of the preceding claims, characterized in that the deposition is carried out in the float-bath chamber.

Process according to one of the preceding claims, characterized in that the deposition is carried out when the glass is at a temperature greater than or equal to the melting point of the metal.

Process according to one of the preceding claims, characterized in that the surface of the glass ribbon is treated before depositing the metal-based reflective layer (3), especially by a contacting/adsorption of vapour of the TiCl.sub.4 type, or by depositing at least one interlayer, especially made of silicon Si, made of an oxide such as aluminium oxide Al.sub.2 O.sub.3, silicon oxide, oxynitride or oxycarbide, SiO.sub.2, SiON or SiOC, zirconium oxide ZrO.sub.2, cerium oxide, titanium oxide TiO.sub.2, zinc oxide ZnO, or boron oxide, yttrium oxide, magnesium oxide, or a mixed oxide of Al and of Si, made of fluorinated aluminium oxide, of magnesium fluoride or of a nitride such as aluminium nitride AlN, silicon nitride Si.sub.3 N.sub.4, titanium nitride, zirconium nitride, or a carbide, which layer is deposited, for example, by chemical vapour deposition.

Process according to one of the preceding claims, characterized in that the metal-based reflective layer (3) is covered with at least one additional layer (5) intended to protect it from oxidation, especially when the glass ribbon is still in the inert and/or reducing controlled atmosphere in which the deposition of the said reflective layer was carried out.

Process according to one of the preceding claims, characterized in that the glass ribbon of a float line is substituted either by a glass ribbon not coming from a float line or a non-continuous glass substrate, such as a glass plate.

Glazing panel (1) obtained by cutting up the float-glass ribbon (10) covered according to the process in accordance with one of the preceding claims, characterized in that it is provided with an aluminium reflective layer (3) having a thickness less than or equal to 30 nm, depending on the solar protection.

Mirror (1) obtained by cutting up the float ribbon (10) covered according to the process in accordance with one of the preceding claims, characterized in that it is provided with an aluminium reflective layer (3) having a thickness greater than or equal to 30 nm.

Glass substrate provided with at least one reflective layer (3) based on a metal of the intermetallic-compound, alloy or eutectic compound type, especially based on at least one of the metals belonging to the group comprising aluminium, zinc, tin and cadmium and, optionally, also comprising silicon, characterized in that the substrate (1) is also provided with an "external" complementary layer (4) and/or with an internal complementary layer (2), with respect to the said reflective layer (3), the complementary layer(s) being intended to ensure its chemical and/or mechanical durability.
