Abstract
A method for creating a glass ceramic component having at least one angle is provided, where the angle is formed as a transition between two legs. The angle is made with a bending radius in the range between 30 mm and 200 mm during conversion of the glass plate in a green glass state to the glass ceramic plate under the effects of a deformation tool.
Claims18
A method for producing a glass ceramic component with at least one angle formed as a transition between two legs, comprising:
- forming the angle with a bending radius in the range between 30 mm and 200 mm during a ceramicizing process by converting a green glass plate into the glass ceramic component with a shaping tool.
A glass ceramic component, comprising:
- an angle is disposed between two legs, the two legs enclosing an included angle (α),
- an angle region on an outer side facing away from the included angle and/or on an inner side facing the included angle has a surface waviness with an Ra value of less than 10 μm at least in the range of ±35% of the plate dimension in the direction of the bending axis, measured from the center of the plate, the long waviness caused by the deformation of the component remaining unconsidered.
12-13. (canceled)
A method for producing a glass ceramic component with an angle between two legs, comprising:
- heating a green glass plate up to a temperature below a ceramicizing temperature to a viscosity sufficient for deformation;
- forming the angle with a bending radius in the range between 30 mm and 200 mm with a shaping tool;
- and
- heating the green glass plate up to the ceramicizing temperature.
