System employing laser heating for the measurement of high-temperature properties of materials over a wide pressure range
Abstract
An equipment system is described that can be used to obtain high-temperature physical property data on refractory materials by means of laser heating. Properties that can be measured are the vapor pressure of solid and liquid phases, the relative rate of vaporization, and emission spectra from solid and vapor phases. Solid phases can be studied by splat-cooling of the liquid and quench-cooling of the solid and vapor. Temperature can be measured both pyrometrically and spectroscopically. In addition, the effects produced by heating a material in an atmosphere of controlled composition and pressure can be studied.
