Latest Patents

The available information identifies one patent for Chung: “Production of MgO Dispersed Bi-2223 Superconductor.” The process mixes partially converted Bi-2223 powder with fine MgO particles, dries the mixture, and places it in a silver tube for drawing, rolling, and heat treatment. It aims to distribute MgO particles smaller than 0.1 micrometers evenly throughout the superconductor, creating flux-pinning centers. Compared with material produced under similar conditions without dispersed MgO, the resulting superconductor is designed to achieve enhanced critical current density under a magnetic field. Chung is credited with 1 patent in the information provided.
