    Jun 01, 2008 Among these the high-energy ball-milling process has many potential advantages. The main advantage is large quantities of samples can be produced in a very short time, and the process is relatively simple and inexpensive. In the present work, ball-milling process has been adapted to prepare nanocrystalline Fe 2 O 3 samples. The optical and defect properties of the prepared nanocrystalline

    Jun 24, 2009 Mechanical alloying (MA) is now being used as a solid-state synthesis route to prepare nanocrystalline alloy/compound powders by milling the elemental powders in a suitable ball mill , , , , . Extreme local pressures and temperatures generated for a short duration during repeated ball-powder-ball collisions lead to the materials transfer by diffusion and eventually, to formation of new phases

    Jun 01, 2006 Nanocrystalline CuFeS 2-chalcopyrite has been mechanosynthesized for the first time at room temperature by ball milling the stoichiometric mixture of elemental powders of Cu, Fe and S under argon atmosphere. It has been noticed that a nanocrystalline CuS has been formed at the early stage of milling. Some additional phases like FeO(OH) and Fe 3 (SO 4) 2 (OH) 5.2 H 2 O are noticed to form

    At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes
