PHYSICAL CHEMISTRY OF HIGH TEMPERATURE MATERIALS
(3.50)
This is an advanced level course designed to address the needs of students in
metallurgy, materials engineering, and ceramics. Application of physiochemical
principles to study the nature of solids, liquids, and gases and heterogeneous
reactions between these phases at elevated temperatures. Transport in
multi-component solids and liquids. Systems of interest include liquid metals,
semiconductors, and other multicomponent solid and liquid oxides.
