Title:
A glass board or a glass ceramic board which reflects infrared rays
Document Type and Number:
Japanese Patent JP5943538
Kind Code:
B2
Abstract:
The glass- or glass ceramic plate (1) comprises a glass- or glass ceramic substrate (2) with a thermal expansion coefficient of 4.2, and a tinoxide layer (3) reflecting infrared radiation formed as single-reflexion layer. The tinoxide layer consists of antimony and is transparent in visible region. The tinoxide layer is formed as crystalline layer and directly adjoins on the glass- or glass ceramic substrate. A bonding layer is arranged between the glass- or glass ceramic layer and the tinoxide layer. An antireflection layer is applied on the tinoxide layer. The glass- or glass ceramic plate (1) comprises a glass- or glass ceramic substrate (2) with a thermal expansion coefficient of 4.2, and a tinoxide layer (3) reflecting infrared radiation formed as single-reflexion layer. The tinoxide layer consists of antimony and is transparent in visible region. The tinoxide layer is formed as crystalline layer and directly adjoins on the glass- or glass ceramic substrate. A bonding layer is arranged between the glass- or glass ceramic layer and the tinoxide layer. An antireflection layer is applied on the tinoxide layer. The glass- or glass ceramic plate has a reflexion grade of greater than 40% in a wavelength of 3000-4000 nm after shaping under thermal load, and an average transmission grade of greater than 70% in the area of the visible light. The ratio of antimony to tin in the tinoxide layer reflecting the infrared-radiation is 2-6%. The tinoxide layer has a thickness of 600-700 nm and is formed for continuous operating temperature of greater than 850[deg] C. The tinoxide layer has a plasma edge of below 2000 nm. An independent claim is included for a method for the production of glass- or glass ceramic plate reflecting infrared radiation.
