Abstract
PURPOSE: To provide an electric contact material having an excellent antiwelding property by a method wherein a Ag-SnO2 powder obtained by internal oxidation of an Ag-Sn alloy is mixed with an Ag powder and Ni powder and mixture is formed and sintered.
CONSTITUTION: In order to distribute a high-melting and high-hardness SnO2 into the base material, an Ag-SnO2 powder obtained by internal oxidation of an Ag-Sn alloy is used. The Ag-Sn powder is provided by melting Ag and Sn to make them fine grains and oxidizing only Sn which is the solute element, selectively. The Ag- SnO2 powder is mixed with Ag powder and Ni powder, and the mixture is formed and sintered to provide an electric contact material of Ag-Ni-SnO2. The preferable composition is Ni: 5W20wt%, SiO2: 3W10wt%, and the remaining Ag. This enriches workability, and resistance to consumption and antiwelding property.
