Recent studies of internal and surface nucleation in silicate glasses
This article reviews recent ndings on internal and surface nucleation in silicate glasses. The internal homogeneous nucleation rates sharply decrease and the induction times increase with the Tg=TL ratio (Tg is the glass-transition temperature and TL is the liquidus temperature). Only systems that have Tg=TL < 0:58 display measurable internal nucleation rates on a laboratory time-scale. Numer...

X - Ray Photoelectron Spectroscopy of Silicate Glasses
X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...
متن کاملNano-Structured Optical Glasses
A variety of oxide glasses and glass-ceramics that contain thermally or optically developed nanostructures will be described along with the properties that derive from the nano-phase, or structural rearrangement. The derived properties include photosensitive, photochromic, photoadaptable color, photorefractive (induced refractive index), photo-machinable, and polarizing.
متن کاملCrystal nucleation in silicate glasses: the temperature and size dependence of crystal/liquid surface energy
The most basic assumption of the classical nucleation theory (CNT) is to treat nucleus/liquid surface energy, r, as a macroscopic property having a value equal to that of a planar interface, r1. Therefore, when the CNT is used to analyze experimental data, the size dependence of surface energy is often neglected. To date, there has been no reliable method to measure the surface energy of the nu...
