Journal Article 2024 02 29 Synthesis, identification and thermal behavior studies of nanoparticles cobalt (II) bromide has been studied in this research. Cobalt (II) bromide was synthesized by planetary high-energy ball mill. The general formula of this compound is CoBr2.6H2O. The synthesized nanoparticles were characterized by Fourier transform infrared spectroscopy and also Size and structure of synthesized nanoparticles were studied by analyzing X-ray diffraction and morphology of surface and structure of synthesized nanoparticles were studied by scanning electron microscopy. This compound has many applications in mineral synthesis as a catalyst. The nanoparticles of CoBr2.6H2O synthesized with smaller size of 35 nm, and its SEM images show that the morphology of particles surface is as like as layer. Also, the thermal behavior of these nanoparticles is considered by using of DTA /TGA thermal analysis.
