Samples of ordinary copper, hot-isotactically-pressed (HIP) copper, and simulated borosilicate high-level waste glass were leached at 25°C, 51°C, and 80°C in solutions simulating brine and silicate groundwaters. It was found that the amount of glass leached increased at higher temperatures, and more leaching occurred in brine than in silicate groundwater. This behavior is predicted by Le Chatelier's Principle. Similarly, more copper was dissolved at higher temperatures, and more was dissolved in brine than in silicate groundwaters.Type
