Title:
微量元素添加Ａｇ合金およびその製造方法
Document Type and Number:
Japanese Patent JP5666156
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the following problems: in Ag dissolved by addition of a deoxidizer thereto, the deoxidizer remains in the Ag, however sometimes the remaining of the deoxidizer can not be allowed upon the production of Ag alloy admixed with a trace amount of element for alloying, and further, Ag has the characteristics of occluding oxygen upon dissolution, and when an element for alloying is added to Ag, the reaction of the element with oxygen to be absorbed into the Ag must be sufficiently considered.SOLUTION: The trace element-added Ag alloy is characterized in that Ag with ≥99.99 wt.% purity in which the content of oxygen is controlled to <10 ppm is blended with one or more kinds selected from among Al, Mg, Si, Zn, Bi, Ge and Pd in an amount of 0.005 to 0.1 wt.% as an additional element.
