The present study focuses on the development of a new route for the synthesis of pure nickel borate nanoparticles using reverse micellar route. Nickel borate nanoparticles (25 nm) were synthesized from a precursor (obtained by reverse micellar route) containing both nickel and boron (nickel nitrate and sodium borohydride as starting materials). Decomposition of the precursor at a temperature of ∼800 °C yielded pure nickel borate nanoparticles. This was confirmed by powder X-ray diffraction and transmission electron microscopy. These nanoparticles show an antiferromagnetic ordering with Nẻel temperature of 47 K.
A new low temperature route has been developed for the synthesis of nanoparticles (20–30 nm) of nickel borate using microemulsion route. These nanoparticles show an antiferromagnetic ordering with Nẻel temperature of 47 K.Figure optionsDownload as PowerPoint slide
