Abstract
The processes were studied concerning the amorphization of three structural types of serpentine minerals (antigorite, lizardite, and chrysotile) and the formation of an active metastable phase resulting from thermal impact. It has been established that the level of antigorite activation is lower than the activation level for lizardite and chrysotile.
