The Institute of Physics offers technology for creating a flexible high-temperature superconductor based on magnesium di
Some of the key advantages of magnesium diboride superconductor are: the possibility of using energy-efficient cryocoolers for cooling; integration into the system of hybrid power transmission line based on the transmission of liquefied hydrogen and high-temperature superconducting cable, the concept and demonstration of which in Russia was realized by the All-Russian Research Design and Technological Institute of Cable Industry.
"Due to the development of cryogenic equipment in the world and achievements in the superconductor manufacturing technologies, the problem of energy saving (leaving the strategically valuable resource—helium) and cheapening the technology of their production is becoming more and more acute," Ruslan Batulin, Asssociate Professor of the Department of General Physics, Head of the Laboratory of Quantum Simulators of the Institute of Physics, says on the matter. "We started to deal with applied superconductivity relatively recently, since 2020, fruitfully cooperating with Professor of Moscow Engineering Physics Institute, Lead Research Associate of the Research Laboratory of Superconducting Energy Systems, Academician Igor Rudnev, to whose memory our recent works published in Superconductor Science and Technology and Russian industry journal Kabeli i Provoda [Cables and Wires] are dedicated."
Speaking about the technology, Batulin explains that a buffer layer is applied to a flexible nickel alloy substrate, a layer of superconductor is deposited on top of it by magnetron sputtering, a protective and stabilizing layer.
Flexible high-temperature superconductor based on magnesium diboride can be used to create various magnetic systems (superconducting magnets and others), current-limiting devices, power cables, motors, generators, energy storage devices.
The development, research and application of flexible superconducting composites based on magnesium diboride for new-generation current-carrying elements were carried out under the grant of the Russian Science Foundation No. 22-72-10088. The invention application was sent to the Federal Institute of Industrial Property.
