Document Type and Number:
Japanese Patent JP5257824
Kind Code:
B2
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.
