Abstract
High-strength vacuum glass is provided. The vacuum glass includes an air-cooled tempered first glass plate; an air-cooled tempered second glass plate that faces the first glass plate via a depressurized layer; and an outer peripheral sealing portion joining an outer peripheral edge portion of the first glass plate and an outer peripheral edge portion of the second glass plate together so as to seal the depressurized layer. The outer peripheral sealing portion contains solder.
Claims10
Vacuum glass comprising:
- an air-cooled tempered first glass plate;
- an air-cooled tempered second glass plate that faces the first glass plate via a depressurized layer;
- and
- an outer peripheral sealing portion joining an outer peripheral edge portion of the first glass plate and an outer peripheral edge portion of the second glass plate together so as to seal the depressurized layer,

2 more elements
A method for manufacturing vacuum glass, comprising:
- a step of preparing a first glass plate and a second glass plate;
- a step of individually tempering the first glass plate and the second glass plate through air cooling;
- a step of opposing the first glass plate and the second glass plate to each other such that a space is formed therebetween, after the tempering through air cooling;
- a step of joining an outer peripheral edge portion of the first glass plate and an outer peripheral edge portion of the second glass plate together by solder so as to seal the space between the first glass plate and the second glass plate;
- and
- a step of depressurizing the space between the first glass plate and the second glass plate through evacuation.
