| titleOfInvention | A kind of preparation method of superfine cupper powder |
| abstract | The invention provides the preparation method of a kind of superfine cupper powder.Described method comprises the steps: to add cupric salt, chlorate and dispersant in deionized water, after stirring and dissolving, form the first mixed solution, it is added thereto to ascorbic acid solution carry out reducing for the first time, after having reacted, gained solution left standstill is layered, topples over upper solution and obtain Cu-lyt. precipitation；Polyphosphate is dissolved in deionized water, then in the Cu-lyt. prepared, add the deionized water dissolved with polyphosphate, it is agitated to form the second mixed solution, in the second mixed solution obtained, add hydrazine hydrate solution again carry out reducing for the second time, isolate precipitation after having reacted, carry out the precipitation obtained washing, being dried to obtain superfine cupper powder.The method of the invention course of reaction is gentle, is suitable to batch production, and the superfine cupper powder good dispersion of preparation, narrow diameter distribution, degree of crystallinity and tap density are high. |
