Abstract
The crystallization of melts prepared in the laboratory but similar in composition to those developed during the firing of Portland cement clinkers has been studied by static and dynamic techniques. These liquids typically contain ∼ 6% SiO 2 and ∼ 22% Aℓ 2O 3 by weight. They have sufficient glass-forming tendencies to permit quenching ca 10 g batches to glass but with slower cooling, partial or complete crystallization occurs at undercoolings up to ∼ 600°C. Low-temperature crystallization occurs in stages: the first recognizable crystalline product of undercooled melts and glasses containing 1–3% Na 2O is proto-C 3A. The latter appears to occur in both cubic and orthorhombic modifications.
