“…In some cases (Grigoryeva, Barinova, Ancharov, & Lyakhov, ; Grigoryeva et al, ), mechanocomposites are formed during the mechanochemical treatment of heterogeneous mixtures. These mechanocomposites are systems with physicochemical properties that are essentially different from those of the initial mixture.…”

At present, “mechanochemistry” is synonymous with “grinding,” according to the views of a significant number of scientists and technologists. Often, one comes across the opinion that “the less the particle size, the better.” The cases of considering chemical reactions occurring during pretreatment, as well as considering changes in the ultrastructure of cell walls are extremely rare. Also, the wrong choice of the type of mechanical impact and the equipment used in most cases leads to excessive consumption of electrical energy and reduce economic efficiency. The review presents the currently available published data on mechanically activated processes for the pretreatment of plant materials and shows that when using mechanical treatment, it is necessary to look more closely at the phenomena occurring, rather than reducing everything to the production of fine and ultrafine powders. As a result of mechanical action, active surface radicals can form, hydrothermal chemical processes can occur, and mechanocomposites can form. The role of interphase processes, changes in surface chemistry, related dimensional effects, and the disordering of the crystal structure and amorphization should be taken into account. In addition, the physicochemical insights in mechanical pretreatment make it possible to more efficiently use the energy delivered to the material, and, consequently, increase the economic efficiency of the activation process.

“…Many examples have been reported where reduction of simple binary oxides by a more reactive metal occurs during high-energy milling [11][12][13][14][15][16][17]. In addition to simple binary oxides, there have also been reports on the mechanochemical reduction of hydroxides [18], sulphides [19], chlorides [20], suphates [21] and ternary complex oxides such as titanates [22], wolframates [23], ferrites [10,[24][25][26][27].…”

A non-thermal route to oxide nanocomposites by mechanochemical redox reactions in the α-Fe 2 O 3 + SnO system is presented. The important impact of the work, from the methodology point of view, is the combined application of 57 Fe and 119 Sn Mössbauer spectroscopies to the study of the mechanically induced redox processes, resulting in the reduction of α-Fe 2 O 3 and the oxidation of SnO. In addition, the obtained product was characterized by X-ray diffraction and transmission electron microscopy.Keywords Mechanochemistry · Redox reaction · Mössbauer spectroscopy V.

“…The most commonly used ceramic particles as reinforcement for the Al matrix are SiC and Al 2 O 3 [7,8]. SiC is a proper choice for high-temperature applications because of its good strength and hardness, acceptable corrosion resistance, low thermal expansion coefficient and high thermal conductivity [9]. Also, Al 2 O 3 can increase the strength and fatigue crack resistance of Al [10].…”

In this Letter, Al-SiC-Al 2 O 3 metal matrix nanocomposite powder was successfully synthesised employing a mechanical alloying technique, through a mechanochemical reaction among aluminium (Al), silicon dioxide (SiO 2) and carbon (C). For commercial purposes, the materials (Al, SiO 2 and C powders) and also the method of synthesis (mechanical alloying) is considered to be cost-effective for production of Al-SiC-Al 2 O 3 nanocomposite. The structural evaluation of powder particles after different milling times was conducted by X-ray diffractometry, and scanning electron microscopy. The results showed that during ball milling Al, SiO 2 and C reacted through a mechanochemical reaction producing Al-SiC-Al 2 O 3 metal matrix nanocomposite powder after 50 h of ball milling and annealing at a temperature of 650°C for 1 h. The crystallite sizes of phases remained in nanometric scale.
