Characterization of Nano-SiC Powder Prepared by High-Energy Ball Milling as a Mechanochemical Process with Subsequent Annealing Process

Abstract

SiC nano-powder compound was prepared by mechanochemical process followed by annealing. Phase evaluation and microstructural changes of the powders during the processes were examined by X-ray diffraction, field emission electron microscopy and transmission electron microscopy analyses. Necessary milling times for initial and perfect formation of SiC nano-powder were 50 and 70 hours, respectively. The mean particles size of specimens annealed via FE-SEM images with 70 hours of milling was found to be less than 100 nm.
