“…Similar results have been reported in many papers such as in [10][11][12]. So we will focus our attention on BM of Ti in air in this paper.…”

“…Although TiN has already been synthesized by different methods, studies on the synthesis of TiN by ball milling Ti in N 2 [10,11] or in NH 3 [12] are still attractive. The resultants obtained by ball milling Ti powder in air are quite different for different authors; for example, TiN was obtained by Zhang et al [13], but titanium oxynitride was obtained by Yang and McCormick [14].…”

“…In the Nb-N system, Liu et al 412 obtained the metastable d 0 -NbN, whereas Ogino et al 405 and El-Eskandarany et al 413 405 Other studies have demonstrated that the mechanochemical syntheses of c-TiN, 419,420 c-ZrN, 421 c-VN 422 and h-AlN 423 can be achieved by milling the powdered metals in a dry ammonia atmosphere and that the milling process is faster than in nitrogen. 420 During the synthesis of c-TiN and c-ZrN, the formation of cubic hydrides was observed during the early stages of milling.…”

“…These phases were transformed into the nitride phases after further milling. 419,421 It has been observed that the c-TiN powders exerted an important extent of nonstoichiometry, with some of the vacancies most likely occupied by hydrogen atoms. 420 Some authors have proposed the use of solid nitrogenous organic compounds to improve the contact of the reactants and to avoid the technical problems associated with the supply of the reactive gas in the solid-gas mechanochemical reactions.…”

Hallmarks of mechanochemistry: from nanoparticles to technology

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).

“…7 The room temperature reaction of an elemental powder with a nitrogen-containing gas can be directly induced by ball milling. 9,10 The use of NH 3 as a nitrogen source during ball milling has attracted considerable interest as a result of the enhanced role of H in the reaction process. 10,11 Under ball impact, NH 3 dissociates into H and N atoms.…”
