Abstract

Fundamentally, any chemical reaction requires mobility of reactant molecules to allow their collisions. However, it is evident that chemical reactions happen even in solid state, where the mobility of chemical species is inherently restricted. Detailed monitoring of mechanochemical reactions recovers regular appearence of amorphous phases in their initial stages, which could play a crucial role enabling solid-state reactions. On the other hand, it is clear that solid-state chemical reactions are initiated by the contact of two substances and take place on the interface. In this line, this presentation is focused to our recent spatially and temporally resolved monitoring of solid-state reactions by means of synchrotron PXRD and microspectroscopic techniques. The emphasis will be on details of the processes and their dynamics in the mechanochemical conditions, as well as during the reactions on solid-solid interfaces, i.e. in the contact zone between two solid reactants. Finally, a comparative analysis of the results, which resolve individual processes enabling solid-state reactivity will be discussed.
