なものとなる。(Problems to be Solved by the Invention) By the way, when the above-mentioned alloy brazing filler metal or composite brazing filler metal is used for brazing ceramics and metal, the interface between the ceramic and the brazing filler metal may be Ti-, Zr, or Hf. However, at the interface between the metal and the brazing filler metal and in its vicinity, Ti, Zr, or Hf reacts with the components in the metal to form a brittle alloy phase, resulting in poor bonding. becomes vulnerable.
そこで本発明は、セラミックスと金属とのろう付けに於

ようにした複合ろう材を提供しようとするものである。Therefore, in order to solve the above problems in brazing ceramics and metals, the present invention diffuses active metals such as Ti contained in the brazing filler metal preferentially to the interface on the ceramic side. The present invention aims to provide a composite brazing material in which the reaction between metals and Ti, etc. is eliminated, and only the brazing material components that do not contain Ti are responsible for brazing with metals.
（問題点を解決するための手段）
上記問題点を解決するための本発明の複合ろう材は、Ｍ

り合わされていることを特徴とするものである。(Means for solving the problems) The composite brazing material of the present invention for solving the above problems is
O is used as intermediate material, brazing metal is on one side and T is on the other side.
It is characterized by being laminated with a brazing filler metal containing any one of i, Zr, and Hf.
（作用）
斯かる構成の複合ろう材は、ろう付は温度に上昇すると
、中間材であるＭｏの両面に張り合わされているろう材
は溶は出すが、Ｍｏがバリヤーの働きをする為、両方の
ろう材が混じり合うことなく、元のろう相成分を保った
状態が維持される。(Function) When the temperature of a composite brazing filler metal with such a structure rises, the brazing filler metal bonded to both sides of the Mo intermediate material will melt, but since the Mo acts as a barrier, both will melt. The soldering fillers do not mix together, and the original wax phase components are maintained.
従って、セラミックスと金属とのろう付けに於いて、セ

Ｔｉ、Ｚｒ、Ｈｆのいずれかが反応し、強固なろう付け
が得られる。と同時に金属はＴｉ、Ｚｒ、Ｈｆを含まな
いろう材のめ反応し、強固なろう付けが得られる。Therefore, when brazing ceramics and metals, if a brazing filler metal containing any one of Ti, Zr, or Hf is placed on the ceramic side and the other brazing filler metal is placed on the metal side facing each other. , Ti, Zr, or Hf reacts at the interface between the ceramic and the brazing metal, resulting in a strong brazing. At the same time, the metal reacts with the brazing material that does not contain Ti, Zr, or Hf, resulting in a strong brazing.
尚、中間材として用いるＭＯはバリヤーの働きをし得る
だけの厚さがあれば充分である。Incidentally, it is sufficient that the MO used as an intermediate material has a thickness sufficient to function as a barrier.
またろう材としては金属と濡れ性の優れたものが望まし

Ｃｕ −Ｎ ｉ系、へｇ−Ｃｕ−Ｉｎ系が適している。In addition, it is desirable that the brazing material has excellent wettability with the metal, such as Ag-Cu series, Ag-Cu-Pd thread, Ag-
Cu-Ni system and Heg-Cu-In system are suitable.
