The aim of this review article on recent developments of mechanochemistry (nowadays established as a part of chemistry) is to provide a comprehensive overview of advances achieved in the field of atomistic processes, phase transformations, simple and multicomponent nanosystems and peculiarities of mechanochemical reactions. Industrial aspects with successful penetration into fields like materials engineering, heterogeneous catalysis and extractive metallurgy are also reviewed. The hallmarks of mechanochemistry include influencing reactivity of solids by the presence of solid-state defects, interphases and relaxation phenomena, enabling processes to take place under non-equilibrium conditions, creating a well-crystallized core of nanoparticles with disordered near-surface shell regions and performing simple dry time-convenient one-step syntheses. Underlying these hallmarks are technological consequences like preparing new nanomaterials with the desired properties or producing these materials in a reproducible way with high yield and under simple and easy operating conditions. The last but not least hallmark is enabling work under environmentally friendly and essentially waste-free conditions (822 references).

“…Many routes were developed to synthesize powders -Selfpropagated High-temperature Synthesis (SHS) reaction, [5][6][7][8] laser pyrolysis, [9][10][11][12][13] fusion synthesis by arc-melting, 14 mechanosynthesis [15][16][17] or thin films by Chemical Vapour Deposition (CVD 18,19 ). Each of these synthesis routes presents both advantages and drawbacks, but they are generally used to produce limited quantities of carbides.…”

“…Zirconium carbide, ZrC has attracted more and more attention due to its outstanding physical and chemical properties, such as high hardness and melting point, good electrical conductivity, high resistance to corrosion and wear, as well as excellent chemical stability [1][2][3]. In addition, ZrC particle is a good obstacle for dislocation movement and can increase recrystallization temperature and hinder grain growth, which lead to strength increment at elevated temperature [4].…”
