Abstract:
The experiment to fabricate large-grain RE–Ba–Cu–O (RE: Rare-Earth element) bulk superconductors in microgravity environment will be performed in the Unmanned Space Experiment Recovery System project. It is difficult to grow high-quality large-grain superconductors on the ground due to the chemical contamination from the substrate and the segregation of liquid phase. Such problems can be overcome by growing large RE–Ba–Cu–O bulk in microgravity environment, in which the bulk can be supported by a seed crystal alone during the crystal growth. In this paper, we describe the experiment plan, the materials composition, design of a temperature gradient furnace and the conditions for the crystal growth.
Not one of the first things we will do. However, for the continued expansion of marketable goods, a great option.
