Chubu Electric Power Boosts Speed of Yttrium-based Superconductive Wire Synthesis
Tokyo, Japan, Oct. 20: Chubu Electric Power has made a breakthrough in faster synthesizing
of yttrium-based superconductive wires. The company has improved on the conventional multi-stage wire synthesis technology to achieve a synthesizing speed of 50m/hr for wires with a current density of 2 million A/cm2, fast enough to make commercial applications feasible; the previous speed was 10m/hr.
The company has also developed a small prototype magnet (77mm high, 64mm in diameter) based on the yttrium wire, which has a magnetic field of 0.65T, the world's highest for yttrium wire-based magnets.
The breakthrough technologies are expected to pave the way for the development of a high-performance superconducting magnetic energy storage (SMES) system magnet and large-capacity, low-loss superconductive cables.
