“…In the case of PG, a similar phenomenon took place, even though it is a single-phase carbon, because the material contains many inhomogeneities which cause cavities to occur that act as blackbody holes. 15 There was some concern that the temperature measurements would be seriously perturbed by the formation of a plasma at the laser focus. A high-voltage spark was discharged at the laser focus to determine whether or not a free-standing plasma formed: a plasma was not observed.…”

Sci.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 splatcooling 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.

Ablative materials play a strategic role in the aerospace industry. The concept of ablation can be related to a geological term at least 160 years old. It is derived from the suppletive past participle of the Latin “auferre” which means to carry away. Ablative materials are used to produce the thermal protection system (TPS) that protects a body from severe heating encountered during hypersonic flight through a planetary atmosphere. The TPS protects the structure, the aerodynamic surfaces, and the payload of missiles, space vehicles, and probes. Ablative materials are also used to produce passively cooled rocket combustion chambers and nozzles, as well as to protect propulsion devices from very high temperature environments.
