CMPR microgravity levitation dataset (in-orbit and ground-matched)

This dataset contains 565 containerless levitation experiment records of high-temperature materials performed both onboard the China Space Station and in ground-matched conditions. It includes key thermophysical properties—liquid-phase density, viscosity, and surface tension—for various alloys and ceramics. Comparative results from Ti-Fe hollow spheres, ZrNbSi, and NiNb alloys reveal consistently lower liquid densities in ground-matched cases, highlighting gravity-induced effects. This dataset provides a valuable reference for understanding gravity’s role in thermophysical behavior and supports microgravity materials research.
