چکیده

In the present research, as the initial phase, the ZrB₂ nano-powders are synthesized at low-temperature through heating a mixture of ZrCl₄, B₂O₃, and Na metal in a molar ratio of 1:2:4 at 650 to 950 ^ºC under pure argon atmosphere. The effect of various parameters involved in the phase transformation and morphology of the ZrB₂ nano-powders are investigated. Also examined systematically are the influence of the stoichiometry of the reactants and different factors bearing upon the granulation of ZrB₂ particles. In particular, we have studied the effects of adding NaCl salt as well as thermodynamic parameters playing roles in the above synthesis process. The morphology of samples is characterized with the help of scanning and transmission electron microscopy. The XRD results shows the presence of ZrB₂ single phase in the product. The obtained images indicate that the synthesized powders have a crystallite nano metric size ranging from 11 to 26 nm. The TEM images and statistical size distribution also reveal the presence of a narrow size distribution of ZrB₂ nano-particles. Also explored and reported are various enhancement parameters like temperature, reaction time, and diluent component on the quality of the synthesized ZrB₂ nano-powders.
