Planetary ball mill for laboratory grinding and milling into the nano range
Ball milling is a typical technique for preparation of powder particles in the metallurgical and ceramic industries. For metallic systems, usually microsize particles are obtained even for an extended milling time because the crushed fine particles can be cold welded again during ball milling [ 9 ].
high energy ball milling and combustion synthesis are the most useful techniques for producing nano-sized ce-ramics and ceramic-composites. The ball milling tech-nique is more environmentally safe than the method of chemical synthesis, producing far less chemical waste [1]. A number of nanostructured metal oxides and their solid
