Low-temperature mass production of superconducting MgB2 nanofibers from Mg(BH4)(2) decomposition and recombination

Massive superconducting MgB2 nanofibers are obtained for the first time from Mg(BH4)(2). The technique optimizes reaction conditions to only 1 h at 460 degrees C and provides nanofibers which exhibited satisfying superconducting properties. The morphology transformation according to temperature changes and the special mechanism of precursor inductive synthesis are discussed.
