Abstract: A process for making semi-reflective metallized glasses containing an anchoring layer, said anchoring layer being deposited by vacuum evaporation from an alloy comprising nickel in an amount of from about 40-70% by weight, chromium in an amount of from about 5-31% by weight, and molybdenum in an amount of from about 3-28% by weight. The anchoring layer may also be deposited from an alloy of nickel, chromium, molybdenum and at least one metal selected from the group of tungsten, iron and cobalt, in an amount of from about 55-75% by weight nickel, iron and cobalt, from about 5-31% by weight chromium, and from about 3-28% by weight molybdenum and tungsten. The anchoring layer is deposited upon the surface of a support glass by vacuum evaporation after which one or more layers may be deposited upon this anchoring layer.

Abstract: Glass sheets having controlled reflection and transmission spectra in which a metallic reflective layer deposited on the surface of a glass substrate is coated with a protective layer consisting of a cadmium and tin oxide mixture wherein the atomic ratio of the cadmium/tin is between about 0.2 and about 10. Alternatively, the metallic reflective layer is deposited on an anchoring layer which is deposited directly on the surface of the glass substrate. The anchoring layer advantageously consists of a cadmium and tin oxide composition identical to that utilized to form the protective layer. According to the present invention, the transmission and reflection spectra of a glass sheet can be modified by controlling the thickness and/or composition of each layer, particularly the composition of one or more of the cadmium-tin oxide layers, to produce glass sheets which exhibit excellent transparency in the visible spectrum and high reflection in the thermal infrared spectrum, thereby reducing energy losses.

Abstract: A glass sheet is provided with a metallic layer and auxiliary dielectric layers, at least one of the auxiliary layers being formed of a deposit of a heavy metal tungsten or molybdenum trioxide. The metallic trioxide may form an anchoring layer, and is advantageously of an interference thickness. Particular procedures for forming electric terminals for supplying heating current to the metallic layer are described. Laminated glazings with an intercalary plastic layer over the metallic trioxide layer are described.
