| Abstract Scope |
Glass dissolution under flow conditions is an area of research that has mainly focused on the analysis of complex glass. The purpose of this study was to examine flow dissolution on a lithium disilicate glass and compare the results to previous research on complex glass. Experiments using deionized water were conducted for up to two weeks at temperatures of 50°C or 95°C and flow rates of 0.333 mL/min and 1 mL/min. Results showed that the total normalized mass loss for silicon was independent of flow rate while for lithium it increased with decreasing flow rate. These trends are different from what has been previously observed in complex glasses where the total normalized mass loss increased with flow rate before becoming independent. It was thought that the difference in trends was due to the presence of a protective layer on complex glasses which does not occur for lithium disilicate glasses. |
