いる。2. Description of the Related Art As a sealing material for high temperature, an adhesive for high temperature in which ceramic particles of silica, alumina, zirconia, etc. are dispersed in water glass or a sealing material for high temperature by softening glass powder, and further gold There is known a method in which a sheet that is hard to oxidize is sandwiched between objects to be adhered, the temperature is raised to the melting point to melt the metal, and the metal is adhered.

合には、温度の上げ，下げにおいて、被接着物の一致化
等の特性が要求される。The sealing material for high temperature is required to have a low gas permeability while adhering an object to be adhered. Further, when considering use at high temperature, characteristics such as matching of adherends are required when raising and lowering the temperature.
【０００４】例えば、ＳＯＦＣへの高温用シールを考え
た発電膜であるイットリア安定化ジルコニア（ＹＳＺ）
とインターコネクターであるランタンクロマイトを接着
すると同時に、燃料である水素又は酸化剤である空気の
シールをする必要がある。For example, yttria-stabilized zirconia (YSZ), which is a power generation film considering high-temperature sealing to SOFC, is used.
It is necessary to bond lanthanum chromite, which is an interconnector, with air, which is hydrogen, which is a fuel, or air, which is an oxidant, at the same time.

での平均値）とほぼ一致させている。接着シール用材料
としては、温度差により構造体を破壊させないという観
点から、熱膨脹率が一致する必要がある。The coefficient of thermal expansion of YSZ and lanthanum chromite is substantially equal to 10.0 × 10 -6 ° C. -1 (average value from room temperature to 1000 ° C.). The material for the adhesive seal needs to have the same coefficient of thermal expansion from the viewpoint that the structure is not destroyed by the temperature difference.

度は約１０００℃であり、また電極の耐熱温度が１３０
０℃程度であるため、融着のための施工温度は１３００

ることが必要である。In consideration of SOFC, the operating temperature is about 1000 ° C., and the heat resistant temperature of the electrode is 130 ° C.
Since the temperature is around 0 ° C, the construction temperature for fusion is 1300
It is necessary that the temperature is not higher than about 0 ° C and that it is cured at 1000 ° C.

０×１０-6℃-1と高い値を得ることも困難である。However, in the conventional sealing material,
It was difficult to satisfy such conditions. In other words, the sealing material obtained by dispersing ceramic particles such as silica, alumina, zirconia in water glass is porous,
It was difficult to obtain perfect gas sealing properties. When glass is used, it is difficult to obtain glass having a softening point higher than 1000 ° C., and at that time, the coefficient of thermal expansion was 10.
It is difficult to obtain a high value of 0 × 10 -6 ° C -1 .

る。In the method of sandwiching a sheet of metal such as gold, which is not easily oxidized, between the adherends and raising the temperature to the melting point to melt and bond the metal, the melting point of the metal is used. There are problems that the range is narrow, the operating temperature range is narrow, or the coefficient of thermal expansion is significantly different.

It is an object to provide a material and a manufacturing method thereof.

That is, a glass material having a low coefficient of thermal expansion and a relatively low softening temperature but a high gas sealing property is used as the base of the sealing material. Next, as means for increasing the coefficient of thermal expansion, magnesia (MgO) having a large coefficient of thermal expansion of 13.8 × 10 −6 ° C. −1 is used. Further, in order to control the softening behavior of the seal material, oxide ceramic powder having a desired coefficient of thermal expansion is added.

いものであれば何を使用してもよい。It is preferable that the base glass has a coefficient of thermal expansion that matches that of the target adherend, but it is predicted to be difficult in reality. To compensate for this, powders having different coefficients of thermal expansion are mixed to control various characteristics. Any powder may be used as long as it is suitable for the purpose and does not melt in glass.
