Mechanochemical effects on talc during fine grinding

2012-3-19  Mechanochemical effect is evident in solids when they are ground with equipment based on impact and shear among the particles (AlWakeel, 2005). Due to the low thermal conductivity characteristics of most nonmetallic solids, the energy delivered by the mill is not stored in the particle as thermal energy, but is applied to the bending and/or breaking of the
