Title:
GLASS WITH SELECTIVELY TRANSMISSIVE AND REFLECTIVE SPECTRUM
Document Type and Number:
Japanese Patent JPS56149347
Kind Code:
A
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.
