A hermetically sealed device comprising a spacing unit and a resistive heating element desirably having a closed-loop structure and process for hermetically sealing a device by using such heating element and spacing unit. The frit can form multiple closed-loops to prevent crack propagation. The heating element can be advantageously made of a metal such as Invar and/or Kovar. The invention enables hermetic frit sealing with low residual stress in the seal for large-area displays. The invention is particularly advantageous for hermetic sealing of OLED display devices having a large area, such as those above 10 inches (25 cm).

A method is disclosed for mechanically bonding a metal component to a ceramic material, comprising attaching an anchor material to at least a portion of one surface of the metal component, and then applying the ceramic material to at least a portion of the one surface of the metal component, such that after the ceramic material solidifies, the anchor material is substantially embedded in at least a portion of the ceramic material, thereby forming a mechanical bond between the metal component and the ceramic material via the anchor material. Also disclosed is an article comprising a metal component and a ceramic material mechanically bonded thereto through an anchor material attached to at least a portion of the metal component.

A mandrel includes a top support a first edge support a bottom support and a second edge support The top support and first edge support make-up a first support section. The bottom support and second edge support make-up a second support section. The first support section and the second support section are disposed relative to one another so as to form an outer circumference. A jack is coupled to the first and second support sections and is configured to move the first and second support sections relative to one another so as to adjust the outer circumference of the mandrel. A locking element removably is coupled to the first and second support sections to selectively prevent relative movement between the first and second support sections.

Methods and apparatus for convective heat treatment of thin glass sheets () are provided. The glass sheets () are held in a fixture () which has a processing volume () which has an open top and an open bottom. A bottom support system () supports the bottom edges of the glass sheets () without blocking a substantial portion of the processing volume's open bottom. A side support system () holds the vertical edge regions of the glass sheets during the convective heat treatment, thus reducing vibration and distortion (warp) of the sheets as a result of the heat treatment. The side support system () can include vertical members () having arms () that can include lips () for engaging the major surfaces of the glass sheets ().

A mold for shaping glass-based material can include a mold body having a surface, wherein at least a portion of the mold body near the surface comprises at least about 90% by weight nickel and from about 0.2% to about 0.35% by weight manganese; and a nickel oxide layer on the surface of the mold body. The nickel oxide layer has first and second opposing surfaces wherein the first surface of the nickel oxide layer contacts and faces the surface of the mold body and the second surface of the nickel oxide layer includes a plurality of grains. The plurality of grains has an average grain size of about 150 μm or less.

A mold for shaping glass can be made by a method that includes providing a mold body having a shaping surface comprising at least about 90% nickel and modifying the composition of the shaping surface of the mold body by exposing the shaping surface to an oxidizing heat treatment. The oxidizing heat treatment may include a ramping heat treatment, a fixed heat treatment, or both the ramping heat treatment and the fixed heat treatment. The ramping heat treatment may include increasing a heating temperature at a rate from about 20 C./hour to about 500 C./hour to a temperature from about 700 C. to about 1000 C. The fixed heat treatment may include holding the heating temperature from about 700 C. to about 1000 C. for a holding time of at least about 5 minutes.
