The Double Vision of Dornford Yatesction of photosensitive additives: (Ag + CeO.), K.O, and A1.O.. The glasses were crystallized in thin layers. The glass was powdered down to grains 0.1–0.5 mm in size and crystallized in 5-cm. porcelain crucibles for 5 min at 800°.

Influence of Crystal-Chemical Similarity on Heterogeneous Crystallization of GlassesSubstances which cause crystallization of a volume-homogeneous microcrystalline structure when added to glasses may be divided into two groups, differing in the mechanism of their action.

Mechanism of the Catalyzed Crystallization of Glasses in the Li2O-Al2O3-SiO2 System with Titanium Di1. We define catalyzed crystallization as volume crystallization occurring in the presence of a catalyst, which may be one of the main glass components or an additional component specially introduced as the catalyst.

Use of the ÉM-7 Electron Microscope for Investigation of Crystal Lattices and Observation of DislocaThe resolving power of the best electron microscopes now in production reaches 8 A, and in some of the most favorable cases it is possible to obtain photomicrographs with resolution down to 4.5 A. The electron microscope is therefore capable of producing visual images of structural microdetails close to the atomic in size.
