| titleOfInvention | A kind of production method of solar cell conductive silver slurry high density silver powder |
| abstract | The present invention discloses the production method of a kind of solar cell conductive silver slurry high density silver powder, reduces silver nitrate using glyoxalic acid as reducing agent, dispersion protective agent component and ligand using glyoxalic acid oxidation product oxalic acid as silver powder.Employing is in reactor and stream adds glyoxylic acid solution, sodium hydroxide solution and liquor argenti nitratis ophthalmicus simultaneously, control material molar ratio is: silver nitrate: glyoxalic acid: NaOH=1:0.5-0.7:1-1.4, maintain reactant liquor pH9-12 and reaction temperature 20-60 DEG C, fed intake rear continuation stirring reaction 0.5-2 hour, makes to react completely and the complete generation gloss of silver-colored grain crystalline.In reactant liquor of the present invention, concentration of silver ions is stablized, easy control of reaction conditions, constant product quality.Present invention substantially reduces macromolecule dispersion protective agent consumption, product aftertreatment technology is simple, and product purity is high. |
