The Effects of the Glass Surface Area/Solution Volume Ratio on Glass Corrosion: A Critical
Review Page 1 ANL-94/34 Chemical Technology Division Chemical Technology Division …

The kinetics of matrix dissolution and alkali-exchange for a series of sodium aluminosilicate
glass compositions was determined at constant temperature and solution pH (D) under …

Borosilicate glass is to be used for permanent disposal of high-level nuclear waste in a
geologic repository. Mechanistic chemical models are used to predict the rate at which …

Static leach tests similar to the PCT were performed for times up to two years to assess the
long-term reaction behavior of high-level nuclear waste glasses similar to those expected to …

Models for borosilicate glass dissolution must account for the processes of (1) kinetically-
controlled network dissolution,(2) precipitation of secondary phases,(3) ion exchange,(4) …

Water contact subjects waste glass to chemical attack that results in the formation of surface
alteration layers. Twoprincipal hypotheses have been advanced concerning the effect of …

Leaching of alkalis from glass is widely recognized as an important mechanism in the initial
stages of glass-water interactions. Pioneering experimental studies [1-3] nearly thirty-five …

When in contact with an aqueous solution, nuclear waste glass is subject to a chemical
attack that results in progressive alteration. During this alteration, constituent elements of the …

Privatized services are being procured to vitrify low-activity tank wastes for eventual
disposalin a shallow subsurface facility at the Hanford Site. Over 500,000 metric tons of low …

Facilities for vitrification of high-level nuclear waste in the United States are scheduled for
startup in the next few years. It is, therefore, appropriate to examine the current scientific …
