Title:
【発明の名称】ナトリウム-硫黄電池のセラミックス製絶縁体と金属部品との接合方法
Document Type and Number:
Japanese Patent JP3376242
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for joining a ceramic insulator to a metal part in a sodium-sulfur cell that can join them firmly in the state that the ceramic and the metal part are joined uniformly all over the joining interface and highly resistant to sodium erosion. SOLUTION: An Al-Si-Mg joining material is placed between the ceramic insulator and the aluminum or aluminum alloy part in a sodium-sulfur cell and the joining material is heated at a temperature lower than the solid phase line and they are pressed in vacuum for joining so that the compression power Y [kg/mm<2> ] and the compression-retaining time X [min] may satisfy the following equations: 0.0661X<2> -1.4593X+10.04<=Y<=0.0473X<2> -1.2211X+11.72 (2<=X<=12).
