化には至っていないという現状である。[Prior Art] Vacuum containers made of glass objects, as typified by color television picture tubes, are widely used for display applications. In particular, a color television bulb requires a degree of vacuum of 10 to 6 Torr or more, and therefore, a bulb serving as a vacuum container is required to have high pressure resistance. The pressure resistance of a normal valve is 3 to 4 kg/cm2 when viewed using the hydrostatic pressure method.
In recent years, as valves have become larger, it has become necessary to further increase their pressure resistance. As already shown in Japanese Patent Publication No. 37-14539 as a method for improving pressure resistance strength, B20316%, Zn04%, pbog, etc. are added to the local part of the valve by weight%.
A method of fusing reinforcing glass consisting of 0% is known. In other words, in order to increase the strength of the bulb, in order to counter the tensile stress acting on the skirt part of the panel, low melting point glass is fused and fixed around the entire circumference of the skirt part, thereby preventing scratches on the glass surface scattered on the skirt part. This is a method to prevent cracks from forming and propagating. Here, the low melting point glass used as this glaze is heated under the heat treatment conditions of the frit seal of the bulb (panel-funnel) (usually 430-
It has sufficient fluidity (maintained at 440℃ for 1 hour) to wet the glass surface, achieves a dense sintered structure with few bores, and has high strength.Furthermore, it has a coefficient of thermal expansion that is thicker than glass (panel). However, the proposed low-melting point glass does not have sufficient fluidity among the above-mentioned required properties and becomes porous, and its thermal expansion coefficient is insufficiently matched. It has the disadvantage that a high pressure resistance of /cm2 cannot be obtained.Therefore, it has not been put into practical use yet.
