GLASS BODY FOR JOINING AND JOINED BODY
Document Type and Number:
WIPO Patent Application WO/2022/131028
Kind Code:
A1
Abstract:
This glass body for joining is joined with a target object. The glass body for joining includes a first glass layer and a second glass layer. The Si molar concentration of the first glass layer is higher than the molar concentration of elements other than oxygen, and is constant. The second glass layer is formed on the surface facing the target object of the first glass layer, and Si molar concentration thereof varies in a direction orthogonal to said surface facing the target object. The thickness of the first glass layer is 1 μm or greater. The thickness of the second glass layer is 5-300 nm. The Si molar concentration in the surface facing the target object of the second glass layer is higher than the Si molar concentration of the first glass layer.
