| titleOfInvention | Preparation method of silver powder with narrow particle size distribution |
| abstract | The application discloses a preparation method of silver powder with a narrow particle size distribution, comprising the steps of: preparing a silver salt aqueous solution with a concentration of 0.01-0.05mol/L, adding 0.1-0.3g/L sodium lauryl alcohol ether sulfate, and making a mixed solution; ascorbic acid and ethylene glycol are made into a reducing agent aqueous solution at a mass ratio of 1.5-3:1, and the pH is adjusted to 10-12, added to the mixed solution in step S1, and stirred and ultrasonically reacted at 30-40°C, Obtain suspension; The silver salt solution of 0.3-0.5mol/L is added dropwise in the suspension that step S2 obtains, and the mol ratio of control step S3 and the silver salt used in step S1 is 20-30:1, stirring and React at 30-40°C, wash the obtained reactant, dry and sieve to obtain the product. The particle size of the silver powder prepared by the method is controllable, the particle size distribution is narrow, the process is simple, and the cost is low, and it is especially suitable for preparing the silver paste on the front side of the solar cell. |
