Description: High temperature superconductors such as YBa2Cu3Ox have great potential in industrial applications
including magnetic levitation, power transmission lines, efficient generators, and microwave
components in telecommunications.|
In general, the properties of YBa2Cu3Ox are enhanced if the materials are fully oxygenated (x~7).
For instance, the transition temperature Tc will decrease sharply if x is reduced to 6.7.
The oxygenation content is temperature dependent and increases as temperature decreases. For
example, in air, x~6.4 at 700°C and -6.95 at 200°C. However, the oxygenation process is often
carried out in the range of 400 - 450°C, because it has been thought that lower temperatures do not
produce adequate oxygen diffusion.
We have carried out oxygenation at temperatures much below the commonly used temperatures and
found that the oxygenation is much more complete, and in turn the properties optimized.
As an example of the improved engineering properties of the more highly oxygenated materials
produced by our process, levitation force in flywheel energy storage will be increased by a factor of
three. The milestone will be the production of a levitator with a levitation force of 30 Newton.
