Abstract
Generally, high-temperature studies of refractory materials are limited by the reactivity of the substance in question with container materials and the total pressure limitation of species-specific detectors such as mass spectrometers. The development of mass spectrometers with extremely high-pumping capability has partially eliminated the pressure restriction, but temperatures above ~2400 K still cause severe container interaction problems. To overcome these problems, we have coupled a Nd:YAG pulsed laser to a high-pressure sampling mass spectrometer. The system utilizes multiple pulses of the laser as successive heating experiments with ionization of the resultant molecular beam by electron impact and mass analysis using a quadrupole mass spectrometer. The technique, laser-induced vaporization mass spectrometry (LIV/MS), has wide potential application to refractory systems and provides time-resolved data on each individual molecular species resulting from the vaporization process.
