Title:
LOW MELTING POINT COMPOSITION, SEALING MATERIAL AND SEALING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/098928
Kind Code:
A1
Abstract:
Disclosed is a low melting point composition which is able to be used in sealing at low temperatures, and which exhibits good wettability to the surface of an object to be sealed. This low melting point composition contains Ag, Br and O as constituent elements. In a predetermined mass of this composition, (a) the proportion of the number of moles of Ag atoms in the total number of moles of all the atoms having positive ionic valences is 60-97%; (b) the proportion of the number of moles of Cl atoms is 0-40%, the proportion of the number of moles of Br atoms is 5-60%, the proportion of the number of moles of I atoms is 0-40% and the proportion of the number of moles of O atoms is 25-90%, respectively in the total number of moles of all the atoms having negative ionic valences; and (c) the proportion of the sum of respective numbers of moles of Cl atoms, Br atoms, I atoms and O atoms in the total number of moles of all the atoms having negative ionic valences is at least 90%.
