Summary

Alpha silicon carbide (α-SiC) powder was comminuted in a planetary mill during the periods of time of 1/2, 2, 4 and 6h. The rotation speed was 300rpm, the milling media used was isopropilic alcohol and the grinding bodies were spheres of zirconia estabilized with ceria. The milling powders were characterized concerning the particle size distribution, chemical composition and density. It was observed a great reduction in the particle size, from micrometric to submicrometric size, showing the capability of producing even nanometric particles.
