TL;DR: In this article, the authors used Urbain's correlation developed for ternary SiO2-Al2O3-CaO mixtures to estimate the viscosity of the liquid phase by considering the evolution of its composition during the solid phase deposit.

TL;DR: In this article, the spreadability of corium-concrete mixtures having large solidification ranges even with viscous silicic melts, the change of microstructure due to cooling rates, the occurrence of a large thermal contact resistance at the corium substrate interface, the presence of a steep viscosity gradient at the surface, the transient concrete ablation.

TL;DR: In this article, the authors describe the physico-chemical analyses made on the corium experimentally obtained from these experiments after cooling, and show that variations of crystalline phases are detected along the sample height.

TL;DR: In this article, the CSC project focused on two key phenomena for external core-catchers efficiency, reliability and safety: spreading and coolability, and provided a lot of results which now constitute a large database and which enabled the qualification of computer codes.

TL;DR: In this article, the aerodynamic levitation technique has been used to achieve contactless surface tension and viscosity measurements of oxide liquids at high temperature (T>2000 K).
