Ball Milling - an overview ScienceDirect Topics

Ball milling is often used not only for grinding powders but also for oxides or nanocomposite synthesis and/or structure/phase composition optimization [14,41]. Mechanical activation by ball milling is known to increase the material reactivity and uniformity of spatial distribution of elements [63]. Thus, postsynthesis processing of the materials by ball milling can help with the problem of minor admixture forming during

2011-10-1  X-ray powder diffraction. Figure 1 shows the evolution of XRPD patterns of mixed lanthanum and iron oxides at different ball milling times. The starting materials were pure Fe 2 O 3 and La 2 O 3, however, due to the highly hygroscopic characteristics of La 2 O 3, most of the La 2 O 3 converts to La(OH) 3 when Fe 2 O 3 and La 2 O 3 are physically ground in air. This was confirmed by the XRPD ...
