Abstract:
|
Pure nickel, copper and zinc nanoparticles were prepared from chlorides of these
elements using ultrasound with three different reducing agents (zinc, aluminum and
magnesium). In the second part, syntheses of nickel-copper alloy and nickel-zinc using
ultrasound were investigated.
The products were characterized by powder X-ray diffraction. The reaction
parameters, such as sonification time, the amount of reagents and reaction conditions were
modified to observe variations in the samples. The particle size of all obtained products was
determined using the Debye-Scherrer equation.
Finally, the as-prepared alloys were investigated by measuring their Curie temperature
using on modified thermogravimetric analysis method. |
