<p>Fibers of Bi(2212) have been produced by pendant drop melt extraction. This technique involves the end of a rod of Bi(2212) melted with a hydrogen-oxygen torch, followed by lowering onto the edge of a spinning wheel. The fibers are up to 15 cm in length with the usual lateral dimensions, ranging from 20 νm to 30 νm. The fibers require a heat treatment to make them superconducting.</p> |
