Dump Lattice Ball Mill

STUDIES OF CRYSTALLITE SIZE AND LATTICE STRAIN IN 2O3

Grinding is carried out under Argon gas atmosphere at 300 rpm milling rotation speed and ball to powder ratio of 10 1 Stearic acid was used as a process control agent PCA to prevent the aggregation of powders during milling The duration of milling process is fixed at 30 min in order to avoid temperature rise and the samples were taken at different times 7 12 15 21 30 38 and 45 h

X Ray Determination of Crystallite Size and Effect of

The high energy ball milling of Ni after 12hours resulted in crystalline size of about 48 nm The lattice strains in nickel Ni powders produced by milling have been analyzed by X ray powder diffraction The lattice strain ε and Debye Waller factor B are determined from the half widths and integrated intensities of the Bragg reflections In Ni the Debye Waller factor is found to increase
