Self-sustaining reactions induced by ball milling: An overview
TLDR
In this paper, the principles of mechanically induced self-sustaining reactions (MSR) are summarized and their relationships with mechanochemistry and SHS are discussed, some interesting from the point of view of fundamental understanding of the process, others are promising as the bases of practical applications.Abstract:
When a highly exothermic powder mixture is activated in a ball mill, a self-propagating process can be ignited after a certain activation time. Exploring the effects of material properties and milling conditions on the ignition time, combined with characterization of reactant mixtures approaching the critical state at ignition, provides useful information on the mechanical activation process. After ignition, the reaction propagates thermally, similar to an SHS process. In this paper, the principles of mechanically induced self-sustaining reactions (MSR) are summarized and their relationships with mechanochemistry and SHS are discussed. Numerous examples are given, some interesting from the point of view of fundamental understanding of the process, others are promising as the bases of practical applications.read more

Effect of dopant loading on the structural features of silver-doped hydroxyapatite obtained by mechanochemical method
TL;DR: In this article, the influence of dopant content on the phase formation, structural properties and morphological features was examined, where the as-prepared powders were single-phase hexagonal HA in the absence of the dopant, however some changes were observed with regards to the peak position and broadening.

An environmentally friendly ball milling process for recovery of valuable metals from e-waste scraps.
TL;DR: Results indicated that the mixture of K2S2O8 and NaCl was the most effective co-milling reagents in terms of high recovery rate and soluble metallic compounds were produced and consequently benefit the subsequent leaching process.

TL;DR: By means of a systematic kinetic analysis of the Bi-Te system reacting to Bi2Te3, a third possibility is established: if one or more of the powder reactants has a low melting point and low thermal effusivity, it is possible that local melting can occur from deformation-induced heating.
