Title:
AMORPHOUS GLASS TABLET AND TABLET-INTEGRATED EXHAUST TUBE
Document Type and Number:
WIPO Patent Application WO/2007/114222
Kind Code:
A1
Abstract:
[PROBLEMS] To provide an amorphous glass tablet of bismuth glass that exhibits
appropriate fluidity at hermetical bonding of an exhaust tube for planar display
unit, etc., being resistant to softening deformation at subsequent exhaust
step at 370° to 420°C, and that avoids the situations of exhaust tube
shifting leading to clogging of exhaust hole and perforation leading to airtightness
deterioration. [MEANS FOR SOLVING PROBLEMS] There is provided an amorphous
glass tablet containing a low-melting-point glass and a refractory filler,
characterized in that the low-melting-point glass has a glass composition containing,
by mole in terms of oxide, 30 to 60% Bi2O3, 10 to 40% B2O3
and 10 to 50% ZnO, and that the refractory filler has a composition containing,
by mole in terms of oxide, 30 to 100% SiO2, 0 to 45% Al2O3,
0 to 35% ZnO, 0 to 20% ZrO2, 0 to 20% TiO2, 0 to 10% Li2O
and 0 to 25% MgO.
