が提案されている。The sealing glass described above can be sealed at about 800 ° C., has a thermal expansion coefficient compatible with that of a metallic material such as Fe-Ni-Co alloy, and is reheated in an exhaust process during manufacturing of a cathode ray tube.

のである。With the recent trend toward larger televisions, the electron guns of cathode ray tubes are becoming larger, and the cathode holding parts of the electron guns are becoming larger accordingly. However, when a large-sized cathode holding component is manufactured using the above-mentioned conventional sealing glass, there is a problem that cracks occur in the sealing glass portion. This is a conventional sealing glass, 30 ~ 300 ℃ (or 400 ℃)
This is due to the fact that it is designed so that the metal material and the thermal expansion are compatible in the low temperature region. That is, it is known that the thermal expansion of these metal materials is abnormally high in a high temperature range of 350 to 450 ° C. or higher. Therefore, the conventional sealing glass is not compatible with the metal material in thermal expansion at high temperatures,
After the sealing, the stress remains in the glass. The stress in this glass has been overlooked because it has little effect when the cathode holding component is small,
In the case of a holding component used for a large-sized cathode ray tube, the amount of metal material or sealing glass used is large, so the amount of stress in the sealing glass is large and cracks and the like are likely to occur.

When ZnO or ZnO.B 2 O 3 is added as a nucleating agent and crystallized, 2ZnO.SiO 2 crystals, Z
In addition to the nO.B 2 O 3 type crystal and the MgO.2B 2 O 3 crystal, BaO.2MgO.2SiO 2 crystal is precipitated. Since this BaO.2MgO.2SiO 2 crystal has a very high coefficient of thermal expansion, the sealing material of the present invention is 30 to 700 ° C.
Shows a coefficient of thermal expansion of 70 to 85 × 10 −7 / ° C.
【０００９】以下、本発明において使用するガラス粉末

い。ZnO is 2ZnO.SiO 2 crystal or Zn
It is a constituent of O · B 2 O 3 system crystals and its content is 4
It is 0 to 60%. If the content of ZnO is less than 40%, it becomes difficult to melt the glass, and if it exceeds 60%, crystallization progresses too much, and sealing and fixing with a metal material cannot be sufficiently performed.

する。B 2 O 3 is a constituent component of glass and also a constituent component of ZnO.B 2 O 3 type crystals and MgO.2B 2 O 3 crystals, and its content is 20 to 25%.
If B 2 O 3 is less than 20%, vitrification becomes difficult,
If it exceeds 25%, crystallization becomes insufficient and the heat resistance decreases.
【００１２】ＳｉＯ2 はガラスの構成成分であるととも

定になり、１５％を越えると溶解性が悪くなる。SiO 2 is a constituent component of glass, and 2ZnO.SiO 2 crystal and BaO.2MgO.2S are also included.
It becomes a constituent component of iO 2 crystal, and its content is 10 to 15
%. If SiO 2 is less than 10%, the glass becomes unstable, and if it exceeds 15%, the solubility is deteriorated.

場合、クラックが発生し易くなる。一方１０％より多い
と溶解性が悪くなる。BaO serves as a constituent component of BaO.2MgO.2SiO 2 crystal, and its content is 0.2 to 10%. When BaO is less than 0.2%, BaO.2MgO.
The amount of 2SiO 2 crystals is reduced, 30-700 ° C
Since the coefficient of thermal expansion does not exceed 70 × 10 −7 / ° C., cracks are likely to occur when used for hermetically sealing a large cathode holding component. On the other hand, if it is more than 10%, the solubility becomes poor.

くなり、金属材料の封着、固定が不十分になる。MgO is a MgO.2B 2 O 3 crystal or BaO.
It becomes a constituent component of 2MgO.2SiO 2 crystal, and its content is 4 to 23%. When the content of MgO is less than 4%, the amount of precipitation of these crystals decreases, and the thermal expansion coefficient at 30 to 700 ° C. does not become 70 × 10 −7 / ° C. or more.
If it is more than%, the crystallization will proceed too much and the residual glass component will decrease, resulting in insufficient sealing and fixing of the metal material.

の支持に支障をきたすおそれがある。By the way, the glass powder used in the present invention contains BaO and MgO as essential components.
・ 2MgO ・ 2SiO 2 crystals are deposited to achieve a high expansion suitable for a metal material. However, if the glass powder alone is hermetically sealed, a large amount of B 2 O is contained in the glass matrix after crystallization. 3 components remain. As a result, the B 2 O 3 component oozes out from the glass surface, which causes a shift in the relative position between the metal and the glass, which may hinder the support of the cathode.

It is 0.02 to 5 parts by weight with respect to 00 parts by weight. If the amount of the crystal powder added is less than 0.02 parts by weight, the above effect is not obtained, while if it is more than 5 parts by weight, the crystallization proceeds too much and the sealing and fixing with the metal material becomes insufficient.
