Abstract

The gas adsorbent of one aspect according to the present invention includes is included in the glass panel unit. The gas adsorbent includes: a substrate made of fiber or a porous substance, of inorganic material; and a liquid containing a getter attached to the substrate.

First claim

The invention claimed is:

1. A glass panel unit comprising:
a first glass panel;
a second glass panel placed opposite the first glass panel;
a seal hermetically bonding the first glass panel and the second glass panel;
an evacuated space enclosed by the first glass panel, the second glass panel, and the seal; and
a gas adsorbent placed inside the evacuated space,
the gas adsorbent including a substrate made of fiber or a porous substance, of inorganic material, and a liquid containing a getter attached to the substrate, and
the substrate having a higher softening point than material of the seal.

2. The glass panel unit of claim 1 , wherein the gas adsorbent is fixed to the seal or is fixed by being sandwiched between the first glass panel and the second glass panel.

3. The glass panel unit of claim 1 , wherein the gas adsorbent is fixed to the seal through hermetically bonding the first glass panel and the second glass panel to each other by heating the material of the seal.

4. The glass panel unit of claim 1 , wherein the inorganic material is glass or metal.

5. A method for manufacture of the glass panel unit of claim 1 , the method comprising:
applying the material of the seal on the second glass panel;
placing the gas adsorbent on the second glass panel; and
hermetically bonding the first glass panel and the second glass panel with the seal heated.

6. The method of claim 5 , wherein the gas adsorbent is placed on the second glass panel to be in contact with the material of the seal.
