Vacuum insulating glazing, a sealing, and a method of producing vacuum insulating glazing

A sealing of a vacuum insulating glazing including first and second glass substrates stacked with a gap, the gap being set at a pressure less than an atmospheric pressure and sealed by the sealing, the sealing comprising:

• a metal component;
• and
• a glass layer that bonds the metal component and the glass substrates,
• wherein a material as the metal component is selected from materials whose tensile strength X (N/mm2) and breaking elongation Y (%) satisfy a relationship Y≧0.10X by a room temperature tensile test (tensile speed:
• 1 mm/min) that is performed after the materials are kept at 490° C. for 40 minutes in an atmosphere.

A method of producing a vacuum insulating glazing including first and second glass substrates stacked with a gap, the gap being set at a pressure less than an atmospheric pressure, the method comprising:

• forming of a first glass layer on the first glass substrate and forming a second glass layer on the second glass substrate;
• forming an assembly including the gap formed therein by assembling a metal component with the first and second substrates such that the metal component contacts the first and second glass layers, a material as the metal component being selected from materials whose tensile strength X (N/mm2) and breaking elongation Y (%) satisfy a relationship Y≧0.10X by a room temperature tensile test (tensile speed:
• 1 mm/min) that is performed after the materials are kept at 490° C. for 40 minutes in an atmosphere;
• heating at least the first and second glass layers of the assembly to bond the first and second glass layers and the metal component;
• and
• depressurizing the gap.
