“…The x-ray diffraction results also revealed the continued existence of the NiO phase for such grinding times. This lends support to the conclusions of Lefelshtel et al 41 regarding the slow comminution kinetics of NiO. However, we do note that the lattice parameter of the spinel phase is very close to that of NiFe2O4, indicating that the spinel does contain nickel, albeit the spinel might be iron-rich in light of the incorporation of abraded iron within it and the presence of remnant NiO.…”

The versatility of mechanochemical processing was investigated in a number of nonmetallic inorganic systems. It is shown that high energy grinding can be used to produce amorphous carbon from synthetic graphite and some forms of natural graphite. Elemental sulfur can likewise be amorphized by prolonged high energy grinding. Phase transformations of aFe2O3 (hematite) and mechanochemical reactions of this phase with ZnO and NiO are strongly influenced by the presence of iron resulting from wear of the grinding media. Thus spinel type ferrites were obtained by grinding of such mixtures for short times (1-3 h in a Spex mill); however, longer grinding times resulted in the formation of FeO or (Fe, Zn)O (when grinding ZnO) or FeO or (Fe, Ni)O (when grinding NiO), presumably as a result of the reaction of mill wear debris with the mill charge. The suspected (Fe, Zn)O phase is most likely a nonequilibrium solid solution. Negligible wear accompanied the mechanochemical synthesis of NiS and ZnS from elemental powders. These sulfides were formed for short milling times. In contrast, sulfides of tungsten were not formed even when rather long milling times were employed. The survey of mechanochemical reactions presented here further reinforces the concept that this low temperature synthesis method is a robust process route for production of a wide range of materials.

“…The grinding can be carried out under either wet or dry conditions; dry grinding is expected to be influenced by the presence of water or hydroxyl groups in the starting materials (2)(3)(4). The influence of water or hydroxyl groups on mechanochemical reactions (soft mechanochemical reactions) (4) has been studied extensively and systematically by Senna and co-workers (4)(5)(6)(7)(8)(9)(10)(11).…”

“…Of particular interest are low-temperature techniques, such as room-temperature ball-milling, which offer the possibility of forming structures exhibiting new and unusual properties. Although the mechanochemical synthesis is of great interest in solid-state physics, chemistry, and material science and has been applied to a wide range of solids (5-7), we found only a few papers in the literature on the application of the high-energy Rball-milling to synthesize a spinel ferrite (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18).…”

“…The investigation of the influence of mechanical activation of the -Fe O /ZnO mixture on the formation of zinc ferrite has revealed that it is possible to achieve the mechanosynthesis of zinc ferrite from zinc oxide and iron oxide powders at room temperature in a planetary mill (11)(12)(13)(14)(15).…”
