TEM characterization and synthesis of nanoparticle B4C by high-energy milling

In this study, nanoparticle B 4 C synthesis was carried out by high-energy milling. For this purpose, B 2 O 3 -C-Mg triple systems were used in the reaction stoichiometric ratios as starting materials in the experimental studies. The reduction process of B 2 O 3 was performed using speks type milling device. The transformation of the ceramic phase of the nanoparticle B 4 C by XRD analysis was examined. In terms of microstructural characterization of its powder shape and morphology, TEM (imaging and selected area diffraction pattern) investigations were conducted. The product synthesized by the leaching process was cleaned from MgO/B 4 C impurities and the production of the nanoparticle B 4 C was performed. After leaching processes, it was determined that some of the synthesized powders were below 50 nm, while others varied between the ranges of 50-350 nm. In TEM examinations of B 4 C particles carried out after leaching process, it was seen that there were twin formations observed as planar error. Depending on the d values calculated by solving the TEM diffraction patterns, the planes represented by nano-sized B 4 C particles were determined.
