Please consider attending the following: MATERIALS ENGINEERING SEMINAR "High Temperature Dissolution Kinetics of Solids in Molten Chloride Salts" By Elizabeth A. Laskowski Purdue MSE Preliminary Exam Advisor: Professor Kenneth H. Sandhage ABSTRACT Chloride based molten salts are of growing interest as heat transfer fluids and thermal energy storage media for concentrated solar power and as solvent baths for spent nuclear fuel processing and precious metal recovery. Sea-derived salts are especially attractive as they offer low cost, abundance, and nontoxic waste in addition to high temperature stability (>650C), low viscosity, and high heat capacity. As new engineering solutions seek to utilize molten chlorides, a significant barrier is finding cost-effective materials that can contain the hot fluids over extended service times due to the corrosive nature of the salts. Sparse literature deeply explores the corrosion kinetics observed for these fluids and generally kinetic assumptions are oversimplified and based purely on static corrosion tests. Literature exploring the kinetics of dissolution in molten oxides lends established models to describe the dissolution behavior observed in molten chloride studies. Understanding the kinetics of material dissolution in these salts will serve new material development to meet the demands of applications. Date: Monday, December 2, 2019 Time: 11:00 A.M.
