Analysis of Quartz Dissolution Rims
Previous thesis work has recently built on the fact that quartz dissolution rims are dependent on dwell temperature. It was sought after to determine if the dissolution rims were also dependent on the temperature at which dwells were held. With results from gradient runs not yielding reliable data, the scope of the thesis was changed. It was thought that analyzing both dwell temperature and time would help determine the onset temperature of quartz dissolution. With analysis of existing samples, which were fired at fixed temperatures and times, the onset temperature of quartz dissolution could be calculated using linear regression analysis. A linear regression analysis was used on each set of samples to obtain the onset temperature. This yielded a linear relationship between dwell time and onset temperature. Error analysis determined that the some differences in rim thicknesses could be attributed to where the quartz particles were sectioned. Future work to further observe this relationship could include a 100-hour run to help further determine the data. Analyzing more rims per sample will result in a more accurate average rim thickness.
