Özet

In this study; W2B nanocrystals were synthesized with B2 O3 /Mg/WO3 starting materials via mechanochemical method. Starting materials were mixed according to the reaction stoichiometry and reduction processes were performed in a planetary ball mill under Argon gas atmosphere. Phase and morphology structure of particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy with energy-dispersive X-ray spectroscopy (TEM/EDX) and the specific surface area was measured by Brunauer-Emmet-Teller (BET) theory. The effect of milling period and molar ratios of starting powders were investigated in detail. Results showed that W2 B nanocrystals were obtained successfully without different tungsten compounds after 30 h milling and purification in 2 M HCl solution. Coaxial/spherical shaped and agglomerated W2 B nanocrystals were observed by microstructural examinations. Crystallite size and specific surface area of the W2 B nanocrystals were determined as 13.61 nm and 18 m2 /g respectively.
