synthesis and characterization of nickel (ii) chloride nanoparticles with the study of their thermal behavior

In this research nanoparticles of nickel (ii) chloride were synthesized and characterized using fourier transform infrared (ft-ir) spectra. nanoparticles of nickel (ii) chloride were prepared by using of ball mill device. a ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. in the research nickel (ii) chloride compound was milled for 10 h at 250 rpm in a hardened stainless steel medium. the resulting nanoparticles were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). the sem imaging technique was applied for the observation of grain sizes and the morphology of the nanoparticles. the debye-scherrer formula was used to confirm the grain sizes determined by the sem slides. xrd results of nanoparticles showed that the crystallite size of reaching 59 mm after 10 h at 250 rpm. thermal behavior of nanoparticles was considered by using of dta /tga thermal analysis device. tga analysis reveals that the synthesized nickel (ii) chloride nanoparticle was thermally stable up to 900°c.
