چکیده: A versatile ball milling process was employed for the synthesis of hexagonal aluminum nitride (h-AlN)
through the reaction of metallic aluminum with melamine. A combined experimental and theoretical
study was carried out to evaluate the synthesized products. Milling intermediates and products were
fully characterized via various techniques including XRD, FTIR, XPS, Raman and TEM. Moreover, a
Boltzmann distribution model was proposed to investigate the effect of milling energy and reactant
ratios on the thermodynamic stability and the proportion of different milling products. According to the
results, the reaction mechanism and milling products were significantly influenced by the reactant ratio.
The optimized condition for AlN synthesis was found to be at Al/M molar ratio of 6, where the final
products were consisted of nanostructured AlN with average crystallite size of 11 nm and non-crystalline
heterogeneous carbon.
