PbO-B2O, thread, PbO-B203-ZnO based glass powder, or a powder composition to which gold M oxide powder, called a suitable filler, is added is used. Among these, a layer-resistant glass composition that is overused for sealing soda-lime glass or potash-soda-lead glass commonly used for lighting has an average linear expansion coefficient of # (hereinafter referred to as α). , 88 to 100
It is required to be able to be fused at temperatures below 0.degree. C., and it is particularly desirable that the fused portion of the lighting tube member be transparent.

Cracks occur in the fused portion due to the difference in amount.

ある。(Means and effects for solving the problems) In order to achieve the above-mentioned object, the present invention comprises mixing low-expansion fire-resistant filler powder with PbO-8203-based low-melting glass.
The glass composition for sealing is characterized in that these components are in the range of 70 to 95% low melting point glass powder, 5 to 30% fire resistant filler powder, in terms of weight percent.

スが被封着１川を濡らさず、封着部の強度および気密性
が損なわれる。また８５％を越えるとαが大きくなシす
ぎる。When PbO is less than 75%, linear fluidity is poor, and the glass does not wet the area to be sealed during sealing, resulting in loss of strength and airtightness of the sealed portion. Moreover, if it exceeds 85%, α is too large.
Ｂ２Ｏ３は、５％未満で社溶融性が悪く、２０％を越え

整のために有効に使用できる。Glass having the above composition has a softening point of 370°C or less, but the α of the glass is 110 to 130 x 10"
``At 7℃, the objective α of the present invention is 88 to 100X.
Not suitable for sealing with materials of about IO/℃. Therefore, in the present invention, a low-expansion refractory filler powder is mixed with the low-melting point glass powder to adjust α. As a low expansion refractory filler powder, α is smaller than that of soft glass,
It is sufficient that α does not change significantly by heat treatment at 450° C. for 30 minutes, and there are many types of materials that have such characteristics, but among them, lead titanate and zirconium silicate are suitable for use in the sealing glass composition of the present invention. It can be effectively used for adjusting α after sealing.

範囲内であれは、それぞれ単独で添加してもよく、両者
を一緒に添加してもよい。Incidentally, lead titanate and zirconium silicate may be added individually or both may be added together within the limited range of the present invention.
前記低融点ガラス粉末と前記耐火性フィラー粉末の混合
比を限定した理由は、次のとうりである。The reason why the mixing ratio of the low melting point glass powder and the refractory filler powder is limited is as follows.
低融点ガラス粉末は、７０％未満では流動性が悪く、９
５％を越えるとαが大きくなシ、封着部にクラックを生
じる。Low melting point glass powder has poor fluidity when it is less than 70%;
If it exceeds 5%, α will be large and cracks will occur in the sealed portion.
耐火性フィラー粉末は、５％未満ではαが大きくなシす
ぎ、３０％を越えると流動性が悪化し、４５０％以下の
温度での封着が困難となる。When the refractory filler powder is less than 5%, α is too large, and when it exceeds 30%, the fluidity deteriorates, making it difficult to seal at temperatures below 450%.

This was stored in a Shirokane Rutsuho and heated in an electric furnace at 1000°C to 100°C.
The mixture was heated to 100° C. and melted with stirring for 1 to 2 hours.

ス組成物を得た。Next, the molten glass was molded into flakes, cooled, and then ground in a ball mill until the average particle size was 10 to 15 μm. Lead titanate or zirconium silicate of comparable particle size was mixed with the obtained glass powder in the amount shown in the table to obtain a glass composition for sealing.

After cooling, the sealed state was observed.

Although the temperature was relatively small at ~95 x 10-'/°C, the wettability was good, and the two sheets of glass were completely connected to form a sealed portion with sufficiently good adhesive strength. Furthermore, there was no devitrification or coloration in the sealed portion, and no cracks were observed. On the other hand, in the sample of Reference Example No. 5, α was a sufficiently small value, but the two sheets of glass could not be sealed under the above sealing conditions, and the glass sheets were easily peeled off.

い。The above has described fusion with soda lime glass, but there are also other fusion bonding methods with potash, soda, lead glass, metals, ceramics, etc., which have an α that is almost the same as soda lime glass. It goes without saying that you can apply it.
