Document Type and Number:
WIPO Patent Application WO/2020/255974
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of providing a method for producing a glass panel unit, said method being capable of making a gas less likely to remain in a vacuum space. A method for producing a glass panel unit (10, 10A) according to the present invention comprises a processing step, an assembling step, a bonding step and an evacuation step. The processing step comprises a getter material production step wherein a getter material containing zeolite and a cerium compound is obtained. In the assembling step, an assembly (100, 101) is prepared. In the bonding step, a first glass plate (200, 20) and a second glass plate (300, 30) are airtightly bonded with each other by melting a peripheral wall (410). In the evacuation step, an internal space (500) is evacuated via a discharge port (700) so as to create a vacuum space (50).
