Investigation and Experimental Study on Microstructure and Characterization of Silicon Carbide Synthesized by High Energy Ball Milling

In recent years, nanopowders have been grabbed the attention in automobile and mechanical industries due to its enhanced mechanical properties such as high strength, hardness, and ductility. In this present work, microstructure and mechanical properties of Silicon Carbide (SiC) powder are investigated. An average size of 20 µ SiC is ground to obtain into nanoscale in a planetary ball mill. The powder is taken in different ball to weight ratios and milled in an argon atmosphere. Sample collection is done for every 10 h and the rotational speed is maintained from 300 to 400 rpm. Eventually, collected samples are characterized by X-ray Diffraction (XRD), Transmission Electron Microscope (TEM), and Energy Dispersive X-Ray Spectroscopy (EDAX). The particle size is availed in smaller grain sizes and varied from 101 to 21 nm after milling of powder with successive time periods.
