Method for synthetizing nano Ag-Ni alloy

The process of composing nanometer Ag-Ni alloy includes the following steps: adding ammonia water to the mixed solution of NiSO4 in 0.70-1.80 mol/L and AgNO3 in 1.00-2.50 mol/L to regulating pH value to 7.5-8.5, adding certain amount of polyvinyl pyrrolidone, heating to 60-80 deg.c, adding reductant...

Zusammenfassung:	The process of composing nanometer Ag-Ni alloy includes the following steps: adding ammonia water to the mixed solution of NiSO4 in 0.70-1.80 mol/L and AgNO3 in 1.00-2.50 mol/L to regulating pH value to 7.5-8.5, adding certain amount of polyvinyl pyrrolidone, heating to 60-80 deg.c, adding reductant N2H4.H2O in 1.50-3.00 mol/L to produce reaction reaction; filtering, washing the obtained powder with alcohol and acetone, drying at normal temperature to obtain nanometer level Ag-Ni alloy powder; sintering at 600-650 deg.c and 15-25 MPa for 10-15min to obtain high density crystallized Ag-Ni alloy. The process features the convenient operation, molecule level mixing of the reactant components and homogeneous micro alloy structure.
