Abstract
A method of treating a glass substrate for bonding. The method includes providing a glass substrate having a fritted portion of a ceramic frit material and a non-fritted portion. At least a portion of the fritted portion includes a bondable surface. The method further includes cleaning and activating the bondable surface for subsequent bonding. The cleaning and bonding steps are carried out by applying an air plasma to the bondable surface.
Claims17
A method of treating a glass substrate for bonding, the method comprising:
- providing a glass substrate having a fritted portion of a ceramic frit material and a non-fritted portion, wherein at least a portion of the fritted portion comprises a bondable surface;
- cleaning the bondable surface for subsequent bonding, the bondable surface portion including a bismuth-based ceramic frit material having a hydroxyl content of greater than 15.0 weight percent after cleaning and activating the bondable surface for subsequent bonding,
- wherein the cleaning and activating steps are carried out by applying an air plasma to the bondable surface.
A pretreated fritted glass substrate for use in subsequent bonding, the substrate comprising:
- a substrate having a fritted portion, the fritted portion including a bondable surface portion, the bondable surface portion including a bismuth-based ceramic frit material having a hydroxyl content of greater than 15.0 weight percent;
- and
- a contaminant layer at least partially contacting the bondable surface portion of the substrate, the contaminant layer having an atomic concentration percentage of Si as silicone of greater than zero and less than 5.0 percent.
A method of providing a glass substrate for bonding to a frame, the method comprising:
- providing a glass substrate having a fritted portion of a bismuth-based ceramic frit material and a non-fritted portion;
- directing an air plasma onto the surface of the fritted portion, the ceramic frit material having a hydroxyl content of greater than 15.0 weight percent after the air plasma and
- applying an adhesive to the fritted portion for subsequent bonding to the frame.
