The partial-replenishment test can be an important tool in exploring the long-term leach behavior of glasses. In order to demonstrate the use of partial-replenishment test data in modeling, experiments were conducted which show that after a relativel

Leach tests on borosilicate glasses using a partial-replenishment technique show that in certain cases large excursions in leach rate may appear at the end of periods ranging between 1 and 20 months. The extent and time of these leach rate transients

Leach tests carried out on tektite specimens (indochinites and australites) under high-dilution conditions show a common behavior characterized by low leach rates (0.00018 g/sq m per d, or 7.2 x 10 to the -12th m/d at 23 C) and an activation energy o

Microtektites, some with a SiO2 content as low as 50%, exhibit a very limited extent of corrosion after having been exposed to interaction with their environment in sea-bed sediments for periods of 105a. Measurements carried out on a bottle-green mic

The effect of the presence of moderate gamma doses (6×104 Gy) on the leaching of glassy and ceramic waste forms has been investigated. It is found that the leach rates are enhanced by
