Method for Manufacturing an Ag-Based Electrical Contact Material, an Electrical Contact Material and an Electrical Contact Obtained Therewith

摘要

A material and method for manufacturing an Ag-based electrical contact material includes synthesizing an intermetallic compound of Me_xSn_y type; ball milling the intermetallic compound; mixing the so obtained intermetallic compound powder with silver powder; packing the mixed powders into a green body; and forming a MeO—SnO₂ cluster structure by internally oxidizing the intermetallic compound Me_xSn_y while sintering the green body.
