Nanoparticles research is gaining increasing interest due to their unique properties, such as increased electrical conductivity, toughness and ductility, increased hardness and strength of metals and alloys, luminescent efficiency of semiconductors, formability of ceramics.
This article discusses about the properties and applications of copper-zinc alloy nanoparticles. Copper is a Block D, Period 4 element, while zinc is a Block D, Period 4 element.
The composition of copper-zinc alloys can vary widely depending on the application. For use as a chemical reagent, zinc typically makes up ~90% of the material. However, alloys with similar amounts of each metal are available.
Copper zinc nanoparticles are flammable solids that are graded as dangerous for the environment with adverse effect on aquatic life.
