Abstract
Glass compositions based on blast-furnace slag are synthesized. Segregation (chemical differentiation) is observed in one of the glass samples based on blast-furnace slag and its influence on the nucleation of crystals in this glass composition is studied. It is found that the dependences of the crystal growth rate of melilite on the thermal processing time are oscillatory in nature with a monotonic decrease in the absolute oscillation amplitude. The crystallization behavior of glass samples without chemical differentiation is compared with that of glass, in which the process of chemical differentiation precedes the bulk nucleation of crystals.
