MAKING AND USE OF TRANSPARENT GLASS-CERAMIC PLATE WITH INFRARED-REFLECTING LAYER |
摘要 |
The transparent bent glass- or glass ceramic plate (1) comprises a glass- or glass ceramic substrate (2) with a thermal expansion coefficient (alpha ) of less than 4.2 and an infrared-radiation reflecting layer (3) formed as a single reflecting layer with a refractive index of greater than 2.2. The infrared-radiation reflecting layer is formed as a crystalline layer, and directly adjoins to the glass- or glass ceramic substrate. An adhesive mediator layer is arranged between the glass- or glass ceramic substrate and the infrared-radiation reflecting layer. The transparent bent glass- or glass ceramic plate (1) comprises a glass- or glass ceramic substrate (2) with a thermal expansion coefficient (alpha ) of less than 4.2 and an infrared-radiation reflecting layer (3) formed as a single reflecting layer with a refractive index of greater than 2.2. The infrared-radiation reflecting layer is formed as a crystalline layer, and directly adjoins to the glass- or glass ceramic substrate. An adhesive mediator layer is arranged between the glass- or glass ceramic substrate and the infrared-radiation reflecting layer. The infrared-radiation reflecting layer has a thickness of 70-200 nm, and a reflection maximum of 800-1700 nm. The transparent glass- or glass ceramic plate has a reflection degree of more than 30% with a wavelength of 700 nm, and an average transmission degree of more than 70% in the area of the visible light. The infrared-radiation reflecting layer is formed for a continuous operating temperature of more than 800[deg] C. An antireflection layer is disposed on the infrared-radiation reflecting layer. The infrared-radiation reflecting layer is formed as a thick layer with a porosity grade of less than 2%. An independent claim is included for an infrared-radiation reflecting transparent glass- or glass ceramic plate. |
