Electrostatic levitation. The UV source causes the metal to be ionized, giving it an electric charge and causing levitation in between the electrodes. The laser melts the metal. The new project involves electromagnetic in stead of electrostatic levitation. Credit: Image courtesy of University of Twente
Crystals that don’t experience mechanical stress during growth, will be of superior quality. Levitate the liquid metal, is the idea behind the new project ‘Perfecting metal crystals’. UT scientists want to grow crystals from a metal melt that is levitated by an electromagnetic field, under vacuum conditions. The liquid is no longer kept within a container and isn’t mechanically stressed by the walls of this container...
