| titleOfInvention | A kind of normal-pressure production method of bigger serface high-purity superfine nickel powder |
| abstract | The invention discloses a kind of normal-pressure production method of bigger serface high-purity superfine nickel powder, this method is with one or both of nickel sulfate or nickel chloride for nickel salt raw material, it is dissolved in the water to form the aqueous solution containing nickel salt, then one or both of ammonium sulfate or ammonium chloride ammonium salt are added in the aqueous solution containing nickel salt, ammoniacal liquor is added, the buffer solution system of nickel metal salt, ammoniacal liquor, ammonium salt is configured to；Surfactant is added in buffer solution system, starting nickel powder and hydrazine hydrate is then added in buffer solution system successively, the mixture as nickel metal salt, ammoniacal liquor, ammonium salt, starting nickel powder and hydrazine hydrate at ambient pressure heats mixture；Or the one kind added in the mixture in potassium borohydride, sodium borohydride, palladium bichloride or silver nitrate aqueous solution, then this mixture is heated at ambient pressure again；After having reacted, by metal nickel powder filtering, washing, the vacuum drying in solution, bigger serface high-purity superfine nickel powder product is obtained, nickeliferous quality is more than 99.5%, and specific surface area is 12~32m 2 /g。 |
