General information
- Short Summary
-
A team of inventors from an established Slovak scientific and research institute has developed a new method for the production of bulk GdBCOAg single-grain superconductor. The present innovative method concerns a new concept of achieving the maximum size of the grown bulk GdBCOAg single-grain superconductor, prepared by growth from the molten components of the superconductor.
The preferred cooperation types are commercial agreement or investment agreement. - Full Description
-
In the field of power electrical engineering, bulk GdBCOAg single-grain superconductors are used in the form of superconducting permanent magnets for the construction of electric rotating machines, frictionless bearings, levitation transport devices, inertia energy reservoirs, magnetic drug transport devices, waste water treatment and so on. This system is particularly interesting because bulk GdBCO-Ag-Pt single-grain superconductors exhibit the highest values of the trapped magnetic field with reduced brittleness due to the addition of silver. A cheaper variant of this bulk superconductor is to replace the expensive platinum with cheaper cerium.
Currently, bulk GdBCOAg single-grain superconductors are produced by growth from a molten mixture of superconductor components. By standard, cerium is added in the form of cerium oxide CeO2. The reaction of the added CeO2 with the GdBa2Cu3O7 superconductor changes the phase composition of the system and an excess of CuO copper oxide appears in the sample. The disadvantage of this solution is that the solidified melt has a different thermal expansion than the bulk crystal and induces mechanical stresses at the crystal/solidified melt interface and can lead to the formation of cracks in the bulk crystal. The above drawback is reduced by alloying the GdBCOAg system with cerium, which will reduce the amount of solidified melt after crystallization of the bulk GdBCOAg crystal. CeO2 is used for this purpose, which causes imperfect growth of the bulk GdBCOAg crystal.
A team of inventors from an established Slovak scientific and research institutions has developed managed to substantially eliminate the above shortcomings by reducing the amount of solidified residual melt after crystallization of the bulk GdBCOAg crystal in air, while achieving more efficient and cheaper production of bulk GdBCOAg superconductors. - Advantages and Innovations
- This new method for the production of bulk GdBCOAg single-grain superconductor brings optimization of the fabrication process, decrease in production cost, increase in production yield and reduction of the melt proportion.
