Surface Chemistry and Slow-Crack Growth Behavior of Fluorozirconate Glassesd to the slow crack growth behavior of these glasses. The surface studies indicate that aqueous environments are especially aggressive. It is found that the penetration and bulk diffusion of molecular water precedes any hydrolysis or dissolution of the glass structure. The chemisorption of water to

Optical Properties of Fluoride Glassesration and properties of the most widely used zirconium tetrafluoride-based compositions are emphasized, and their optical behavior contrasted with that observed in silicate glasses and other vitreous fluorides. The topics addressed include ultraviolet and infrared absorption, light scattering, refr

Vapor Deposition of Fluoride Glasses materials and direct fabrication of fluoride preforms by chemical vapor deposition (CVD) are discussed. The results of CVD of metal fluorides for fabrication of ultra-low-loss fiber optics are discussed and recent progress in deposition of fluoride glass is noted.
