SILVER BASED ALLOY WITH HIGH CORROSION RESISTANCE AGAINST THE ATMOSPHERE WHEN IT USED AS REFLECTIVE LAYER BY SELECTIVELY COMPRISING INDIUM, TIN, ANTIMONY AND BISMUTH, AND ITS USE

摘要

PURPOSE: To provide a silver based alloy which can be used as a reflective layer having reflection factors in a visible ray range of 90% or more of the sunlight and displays high corrosion resistance against the atmosphere including sulfur, and applications of the alloy. CONSTITUTION: The silver based alloy comprises 0.01 to 5.0 wt.% of indium(In) an/or tin(Sn) and/or antimony(Sb) and/or bismuth(Bi); and the balance of silver(Ag), wherein the alloy comprises 0.5 to 3.0 wt.% of indium(In) an/or tin(Sn) and/or antimony(Sb) and/or bismuth(Bi); and the balance of silver(Ag), wherein the alloy comprises 0.5 to 1.0 wt.% of indium(In) an/or tin(Sn) and/or antimony(Sb) and/or bismuth(Bi); and the balance of silver(Ag), wherein the alloy comprises 0.5 or 1.0 wt.% of tin(Sn), and the balance of silver(Ag), wherein the alloy comprises 0.5 or 1.0 wt.% of indium(In), and the balance of silver(Ag), and wherein the alloy comprises 0.5 wt.% of tin(Sn), 0.5 wt.% of indium(In) and the balance of silver(Ag).
