GLASS PANEL UNIT, GETTER MATERIAL, GETTER MATERIAL COMPOSITION, AND METHOD FOR MANUFACTURING GLASS PANEL UNIT
The problem to be overcome by the present disclosure is to provide a glass panel unit having a getter material that achieves a sufficient adsorption performance in a low-pressure range and also provide such a getter material. A glass panel unit 10 includes: a first glass pane 20; a second glass pane 30 facing the first glass pane 20; a frame member 40; an evacuated space 50; and a gas adsorbent 60. The frame member 40 hermetically bonds the first glass pane 20 and the second glass pane 30. The evacuated space 50 is surrounded with the first glass pane 20, the second glass pane 30, and the frame member 40. The gas adsorbent 60 is placed in the evacuated space 50. The gas adsorbent 60 contains a getter material. The getter material contains a plurality of particles of a zeolite crystal. At least one particle accounting for a half or more of a total weight of the plurality of particles has a particle size equal to or greater than 200 nm. An activable temperature of the at least one particle is equal to or lower than 400°C.
