Abstract

The crystallization behaviors of stoichiometric feldspar gels and glasses before and after seeding have been compared, and the role of epitaxy in their crystallization upon seeding has been studied. The crystallization products were mainly determined by X-ray diffraction (XRD) analysis and epitaxy upon seeding was examined with a scanning electron microscope (SEM), and energy dispersive spectrometry (EDS). It was found that upon isostructural seeding, Na- and K-feldspars crystallized epitaxially from their gels and/or glasses. Little or no seeding effect was found in CaAl₂Si₂O₈ and SrAl₂Si₂O₈ gels and glasses. Isostructural seeding in BaAl₂Si₂O₈ gels increased the formation of Ba-feldspar (monoclinic celsian) epitaxially, whereas without seeding hexacelsian was the crystallization product.
