Millimeter-wave (MMW), radiometry, calorimetry, high power gyrotron radiation, directed energy, real-time monitoring, rock vaporization
Quantitative studies can be performed in situ of the thermodynamic properties of materials to extreme high temperatures that would be of value for determining the directed energy penetration requirements into hard rock. The high temperature engineering limits of other refractory and structural materials could be studied.
The vaporization parameters of rocks, concretes, and refractory ceramics are not readily available.
This invention describes a procedure to carry out MMW studies of rock fusion and vaporization that is applicable to all refractory materials. This includes using MMWs to melt and vaporize rock and measuring the MMW emissivity of molten rocks, the dynamics of phase transitions, and the phase transition temperatures including vaporization.
