FORMULATION OF AN AG-SN INTERMETALLIC COMPOUND

A method for synthesising an Ag-Sn intermetallic compound comprising the following sequence of steps: - a step of providing a mixture (E1) during which a solution of a mixture of a silver salt and a protective agent in a polyol solvent is produced, - a first heating step (E2) during which the soluti...

Zusammenfassung:	A method for synthesising an Ag-Sn intermetallic compound comprising the following sequence of steps: - a step of providing a mixture (E1) during which a solution of a mixture of a silver salt and a protective agent in a polyol solvent is produced, - a first heating step (E2) during which the solution is heated to a temperature T1 greater than or equal to 140°C and less than or equal to 180°C for a time t1 greater than or equal to 5 minutes and less than or equal to 1 hour, - a step of introducing a tin salt (E3) during which a tin salt and sodium hydroxide are introduced into the solution, - a second heating step (E4) during which the solution is heated to a temperature T2 greater than or equal to 140°C and less than or equal to 180°C for a time t2 greater than or equal to 5 minutes and less than or equal to 1 hour, - a reduction step (E5) during which a reducing agent is introduced into the solution, - a third heating step (E6) during which the solution is heated to a temperature T3 greater than or equal to 160°C and less than or equal to 240°C for a time t3 greater than or equal to 30 minutes and less than or equal to 24 hours, and - a recovery step (E7) during which the Ag-Sn intermetallic compound obtained is recovered.
