Dissolution–precipitation–decomposition–crystallization mechanism of self-propagating high-temperature synthesis of Al3Ni2

Combustion synthesis: A new approach for preparation of thermoelectric zinc antimonide compounds

“…This reaction mechanism named as dissolution-precipitation mechanism has been largely developed in combustion literature devoted to solid-solid reactions. The most important examples cited in the literature involve Ni-Al system [12,13] and Ti-C system [14][15][16]. In each case, melting of the reactants gives rise to ignition of the reaction between the elements and after that, a dissolution-precipitation mechanism was evidenced giving rise to the crystallisation of the binary phase.…”

The application of statistical methodology to the analysis of time-resolved X-ray diffraction data

“…Studies of solid-state reactions have traditionally employed methods such as X-ray diffraction, and have been performed by 'quenching', in which the reaction is suddenly arrested by crash-cooling. 7,8 Unfortunately, when analysing a quenched sample, one cannot be sure that it is truly representative of the reaction matrix because of the possibility that a species present is metastable and has been altered by the quenching process.…”
