Abstract
The preparation features using water solution containing AgNO3 0.01-0.04%, Cu(NO3)2 0.01-0.2% and hydrazine hydrate 0.01-0.5%. After water solution of AgNO3 and water solution of Cu(NO3)2 are mixed, water solution of hydrazine hydrate is added, and through stirring for 10-15 min, filtration, washing and low- temperature drying, is obtained nanometer silver-copper alloy powder with copper content of 0.01-10%. Compared with available technology, the alloy powder size is nanometer level and using the alloy powder in conducting size can result in saving silver by 30-60% and less environment pollution.
Description
The present invention relates to a kind of compound of silver, particularly a kind of preparation method of nanometer silver-copper alloy powder.
Silver powder is widely used in industries such as automobile, electronics as the electrocondution slurry main component.The granularity of present commercially available silver powder is a micron dimension, and the silver powder minimum particle size is 0.5 micron.As " noble metal " magazine 1993 14 the 3rd phase of volume " electrocondution slurry with the research of silver powder " method that a literary composition is provided, the particle mean size of acquisition is 9.6 microns a silver powder.Prepare in the silver powder process in existing chemical method, used chemical reagent toxicity is big, if any also used cyanide, environmental pollution is serious, the silver powder granularity is bigger simultaneously, the consumption of silver is also bigger.
The object of the present invention is to provide a kind of preparation method of nanometer silver-copper alloy powder, adopt better simply technology, the preparation nanometer silver-copper alloy powder replaces micro-silver powder, can economize on silver-colored 30-60%.Reduce in the preparation process pollution simultaneously to environment.
The present invention is a kind of preparation method of nanometer silver-copper alloy powder, it is characterized in that with silver nitrate, copper nitrate and hydrazine hydrate be raw material, and its prescription is:
A) silver nitrate aqueous solution, concentration are 0.01～0.4%
B) copper nitrate aqueous solution, concentration are 0.01～0.2%
C) hydrazine hydrate aqueous solution, concentration are 0.01～0.5%
By required copper content, select A, B liquid proportional, after the mixing, in stirring, add C liquid lentamente, continue to stir after ten to 15 minutes, obtain nanometer Ag-Cu alloyed powder precipitation, washing after filtration,, low temperature drying, just obtain copper content and be 0.01～10% nanometer Ag-Cu alloy washing, low temperature drying, just obtain copper content and be nanometer Ag-Cu alloyed powder of 0.01～10%, powder granularity is 25～60nm.The fine silver powder that Fig. 1 records for X-ray diffractometer and the X-ray diffractogram of Nano Silver-5% copper alloy, abscissa is the angle of diffraction (2 θ angle) among the figure, and unit is degree, and ordinate is a relative intensity.X-ray diffractogram shows that resulting is single-phase yellow gold powder.
With existing technology relatively, advantage of the present invention is: the one, replace micro-silver powder with nanometer silver-copper alloy powder, and the particle mean size of nanometer silver-copper alloy powder is 25 to 60nm, can save silver consuming amount 30-60%; The 2nd, used chemical reagent does not contain cyanide and other environment is produced the reagent of severe contamination, helps environmental protection.
The fine silver powder that Fig. 1 records for X-ray diffractometer and the X-ray diffractogram of Nano Silver-5% copper alloy.
Embodiment:
By following concentration preparation silver nitrate, copper nitrate and hydrazine hydrate aqueous solution,
A) concentration is 0.036% silver nitrate aqueous solution, 250c.c.
B) concentration is 0.04% copper nitrate aqueous solution, 250c.c.
C) concentration is 0.2% hydrazine hydrate solution, 500c.c.
After A, the mixing of B liquid, C liquid is slowly joined in A, the B mixed liquor, in stirring, add C liquid lentamente, continue to stir ten to 15 minutes, reaction finishes.After filtration, after the washing, low temperature drying, just obtain copper content and be 5% yellow gold powder, granularity is 23nm.
