<P>PROBLEM TO BE SOLVED: To provide a brazing filler metal for atmospheric joining which can easily join metals to each other, ceramics to each other, and a metal and ceramics in the air without using flux, regarding a brazing filler metal for atmospheric joining and a joined body being a sealing material for a solid oxide type fuel cell, particularly, the brazing filler metal for atmospheric joining for maintaining air-tightness of a fuel gas and an oxidizer gas between the components of a solid oxide type fuel cell operating at 600 to 800°C and a joined body with a sealing structure including the brazing filler metal for joining. <P>SOLUTION: The brazing filler metal for atmospheric joining is composed of Ag as the main component; Ge, Cr or their oxides, and inevitable impurities as the balance, and is made into a composite oxide mainly composed of Ge and Cr in the joining stage in the atmosphere. <P>COPYRIGHT: (C)2010,JPO&INPIT |
