Abstract

A method for laminating glass, glass-ceramic, or ceramic layers. The method comprises providing a first layer of glass, glass-ceramic, or ceramic, wherein the glass, glass-ceramic, or ceramic of the first layer is electromagnetic radiation-sensitive or has an electromagnetic radiation susceptor disposed on it; stacking a second layer of glass, glass-ceramic, or ceramic on the first layer; and irradiating the stack with electromagnetic radiation to laminate the first and second layers.

Claims

1. A method for laminating glass, glass-ceramic, or ceramic layers, which comprises:

providing a first layer of glass, glass-ceramic, or ceramic, wherein the glass, glass-ceramic, or ceramic of the first layer is electromagnetic radiation-sensitive or has an electromagnetic radiation susceptor disposed on it;

stacking a second layer of glass, glass-ceramic, or ceramic on the first layer; and

irradiating the stack with electromagnetic radiation to laminate the first and second layers.

2. The method of claim 1, wherein the glass, glass-ceramic, or ceramic of the first layer is electromagnetic radiation-sensitive.

3. The method of claim 2, wherein the glass, glass-ceramic, or ceramic of the first layer has a dielectric tan δ

of 0.02 or greater during irradiation.

4. The method of claim 1, wherein the glass, glass-ceramic, or ceramic of the first layer is an alkali-containing glass or peralkaline glass.

5. The method of claim 1, wherein the glass, glass-ceramic, or ceramic of the first layer is a glass-ceramic comprising an electromagnetic radiation-sensitive crystal phase.

6. The method of claim 5, wherein the glass-ceramic comprises a nephaline or rutile phase.

7. The method of claim 1, wherein the glass, glass-ceramic, or ceramic of the first layer has an electromagnetic radiation susceptor disposed on it.

8. The method of claim 7, wherein the susceptor has a dielectric tan δ

of 0.05 or greater during irradiation.

9. The method of claim 7, wherein the susceptor is a layer disposed on a surface of the glass, glass-ceramic, or ceramic of the first layer and contacting the second layer of glass, glass-ceramic, or ceramic in the stack.

10. The method of claim 9, wherein the suscepting layer comprises indium tin oxide, antimony tin oxide, zinc oxide, carbon nanotubes, alkali or alkaline earth metals, or titania.

11. The method of claim 1, wherein the glass, glass-ceramic, or ceramic of the first layer is electromagnetic radiation-sensitive and further has an electromagnetic radiation susceptor disposed on it.

12. The method of claim 1, wherein the second layer of glass, glass-ceramic, or ceramic is electromagnetic radiation-sensitive or has an electromagnetic radiation susceptor disposed on it.

13. The method of claim 1, wherein the second layer of glass, glass-ceramic, or ceramic is not electromagnetic radiation-sensitive and does not have an electromagnetic radiation susceptor disposed on it.

14. The method of claim 1, which comprises irradiating the stack with electromagnetic radiation at a frequency of from 3 MHz to 300 GHz.

15. The method of claim 1, which comprises irradiating the stack with a gyrotron at a frequency of from 28 GHz to 200 GHz.

16. The method of claim 1, which comprises irradiating the stack only at the interface of the first and second layers.

17. The method of claim 1, which comprises irradiating the entire volume of the stack.

18. The method of claim 1, which comprises applying a pressure of at least 13 kPa to the stack during irradiation.

19. The method of claim 1, which comprises applying a vacuum of less than 250 mmHg to the stack during irradiation.

20. The method of claim 1, which comprises applying external heat to the stack during irradiation.
