Abstract

The effect of mechanical treatment on phase transitions of calcium borate-colemanite was studied. The decrease in the particle size of the original material and the increase in its internal structural disorder affect the thermal stability, characteristic temperatures and thermodynamic parameters of phase transitions such as structural relaxation and crystallization, occurring during the heating of this amorphous material. With increasing degree of amorphization of colemanite a change is observed in the structural mechanism of its crystallization.
