Introduction

Nanoparticles research is growing widely as they can be easily altered by changing their shape, size and chemical properties. Nanoparticles have unexpected optical properties, and produce quantum effects.

Nickel is more commonly found in ores and sometimes found free in nature. It can be alloyed with tungsten, molybdenum, chromium, iron and other metals to form corrosion-resistant alloys. It is electrically ­­conductive and hence used for several applications. Nickel nanoparticles are available as nanofluid and in passivated, ultra high purity, high purity, coated and dispersed forms.
