【 摘 要 】

This report documents the results of applying thermal analysis methods to the characterization of the properties of Slurry Mix Evaporator (SME) product samples as a function of temperature. The goal of the research program was to determine if various thermal analysis methods could aid in measuring melter feed melt rate, study the impact of post SME additions of formic acid, and aid in developing a better understanding of melter cold cap chemistry. The thermal analysis methods tested in this program included Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), and Accelerating Rate Calorimetry (ARC). The samples used in the study were from a study on the impact of acid stoichiometry and redox on melt rate.
