Abstract :
We report results from the Space Shuttle experiments Colloidal Disorder–Order Transition (CDOT) 1 and 2. The phase diagram of colloidal hard spheres is measured in microgravity avoiding the effects of sedimentation and convection that arise with normal gravity. For samples in the crystal–liquid coexistence region we observed a dendritic growth. For high concentration samples near random close packing we observed crystallization and no evidence for a glassy phase.
