General information
- Short Summary
-
This technology offer presents a novel technology for the production of ultralight superconductive wire based on magnesium diboride core stabilized with unique aluminum composite sheath has been developed.
Based on the commercial or suplier agreement, partners for selling/licencing the technology are sought. - Full Description
-
Two Slovak research institutes are public research institutions focused on developing new materials and technologies in electrical and mechanical engineerings. The offered superconductor is the common result of their coopertion and is aimed for applications particularly in the space program, aerospace area and energy industry, where low rotational and total weight of devices are desired.
Nowadays superconductor designs, i.g. NbTi, Nb3Sn as well as MgB2, use a sheath mostly based on Cu, Cu alloys and Cu metal matrix composites (MMC). Due to its high density, Cu, contributes heavily to the overall mass of the superconductive wire. Similarly the use of other sheath materials, i.g. niobium (Nb) or steel, also leads to the same effect. Consequently, even for a lightweight MgB2 core, technical solutions of superconductors which utilize Cu sheath are known.
The above-described drawbacks are largely eliminated by the novel superconductor with the MgB2 core and the sheath from Al based MMC. The principal idea lies in the fact that the superconductor sheath is formed by deformation in the form of a tube. The microstructure of sheath consists of near- or sub-micrometre Al grains, stabilized and strengthened by a small amount of homogeneously dispersed nanometric Al2O3 particles, which forms in situ in Al matrix. - Advantages and Innovations
- The protected technology yields superconductor with significantly lower mass (at least 2.5 - 3 times less) than the standard solutions based on NbTi, Nb3Sn and MgB2 core with an outer copper (Cu) sheath; economically meaningful fabrication process which is feasible at a large scale; excellent combination of mechanical properties of the superconductor at room and cryogenic temperatures provided by the sheath; good superconducting electrical properties and thermal conductivity.
