Resum

Overcooling of a cryolite (Na3 AlF6 ) melt gave rise to a granular aggregate. This aggregate can be regarded as the result of a process of homogeneous primary nucleation. Due to the crystallization pressure exerted by the cryolite during cooling, the grains are progressively embedded by a matrix constituted by the contaminant elements (e.g., Si) of the system. Abundant polysinthetic twins are here interpreted as an experimental evidence of processes related to the ferroelastic transition, that took place during cooling.
