Preparation method of silver nickel composite material

A method for preparing silver-nickel composite material, to a silver-nickel composite material. Provides a method of a silver-nickel composite material is dispersed. Ag 2 NiO Synthesis 2 crystals: mixing nickel nitrate solution and silver nitrate solution, sodium hydroxide solution was added to the reaction solution at 230 to 270 ℃ incubated least 72h to give the Ag 2 NiO 2 crystals; in H 2 + N 2 atmosphere, reducing Ag 2 NiO 2 crystal; the Ag 2 NiO reduction product ball 2 crystals, to obtain micron sized silver nickel composite powder; microscale silver nickel composite powder tabletting, sintering under a protective atmosphere. Since in the synthesis Ag 2 NiO 2 process has been silver, nickel atoms are arranged, it is possible to achieve both mixing on the atomic level, the prepared silver-nickel composite nickel-silver material distribution is relatively uniform matrix. Simple process, short cycle, low cost and suitable for industrial production.
