Mechanically Induced Reactivity of Solids

Ursula Steinike, Hans-Peter Hennig
1992 Kona : Powder and Particle  
The action of mechanical energy on solids effects changes to their structure. The resulting structural defects lead to a storage of energy in the solid, which may raise its chemical reactivity.  ...  Investigations on the mechanically induced reactivity of solids have been carried out with the specific aim of influencing reaction processes in order to obtain high yields, high reaction velocities or  ...  The reactivity of solids may often be considerably enhanced by mechanical treatment.  ...
