Title:
BRAZING MATERIAL FOR BONDING IN ATMOSPHERE, BONDED ARTICLE, AND CURRENT COLLECTOR MATERIAL
Document Type and Number:
WIPO Patent Application WO/2012/077733
Kind Code:
A1
Abstract:
Provided are: a brazing material for use in the bonding in atmosphere, which can be melted at a temperature equal to or lower than the melting point of Ag and enables the improvement in high-temperature durability of a bonded article; and a bonded article and a current collector material each having high-temperature durability.
The brazing material for use in the bonding in atmosphere contains Ag, B and Si as essential components, wherein the sum total of the ratios of the contents of the constituent elements other than Ag is set at more than 50% by volume and 90% by volume or less, the ratio of the content of Si in the total content of the constituent elements other than Ag is set at more than 22% by volume, and the ratio of the content of B in the total content of the constituent elements other than Ag is set at more than 14% by volume. For example, as illustrated in fig. 4, in a bonding layer (13) in a bonded test specimen after the retention of a sample of the present invention at a high temperature, a void (16) (fig. 6) as observed in a bonded test specimen after the retention of a comparative sample is not observed, and it is confirmed that the brazing material is fully melted and good air-tightness can be kept after the retention at a high temperature for a long time.
