Abstract
In processing and end-use environments, and particularly nuclear fission reactor excursions, inorganic materials can be subjected to temperatures where liquids and vapors are significant components of the materials system. Classical characterization and thermochemical methods fail at temperatures beyond about 3000 K, due to the reactivity of container materials. Use of a pulsed laser beam as a localized heat source avoids this limitation. Coupling laser heating with molecular beam sampling and mass-and optical-spectroscopy aloows us to characterize the thermochemistry of liquid-vapor systems at temperatures of 3000-5000 K, pressures of 0.01 to 20 bar (1 bar=105 Nm-2), and on a nanosecond order-or-magnitude time scale.Citation
