Abstract:

The crystallization behavior and resultant microstructures of nepheline glass-ceramics prepared by nonconventional final crystallization heat treatment were studied using DTA differential thermal analysis, X-ray diffraction, and electron microscopy. Heat treatments employed various nucleation holds followed by a rapid increase in temperature to effect final crystallization. Comparisons were drawn between the crystallization sequence and microstructures observed in the present study with those obtained by conventional processing of the same parent glass.
