High-Temperature Chemistry

In this course, a general overview of chemistry in non-aqueous solvents at high temperatures will be presented through concepts such as chemical reactivity and the physicochemical and thermochemical properties of oxides, salts, and molten metals. Several case studies will be discussed, particularly those related to the fuel cycle and recycling chemistry.

The objective of this course is to present the properties of nonaqueous solvents at high temperatures (molten non-oxide salts, liquid metals) and physicochemical phenomena (solvation, nonprotonic acidity, redox reactions) in order to facilitate an understanding of glass-making processes and the purification of materials via pyrometallurgical methods.
