Vaporization coefficients of SiO2 and MgO
TLDR
In this article, the vaporization coefficients for both SiO2 (cristobalite) and the (100) face of MgO were measured with free surface (Langmuir) vaporization using a vacuum thermogravimetric apparatus.Abstract:
The vaporization coefficients are measured for both SiO2 (cristobalite) and the (100) face of MgO. These oxides vaporize congruently and are studied with free surface (Langmuir) vaporization using a vacuum thermogravimetric apparatus. The measured fluxes are compared to the calculated equilibrium fluxes to determine vaporization coefficients. Post-vaporization microstructures are also examined and discussed in regard to the vaporization process.read more

Critical point and supercritical regime of MgO
Tim Bögels,Razvan Caracas +1 more
TL;DR: The position of the critical point determines the top of the liquid-vapor coexistence dome, and it is a physical parameter of fundamental importance in the study of high-energy shocks, including those associated with large planetary impacts as mentioned in this paper .
