Direct pyrolysis method for superconducting crystalline MgB2 nanowires
Abstract
<p>A direct pyrolysis route from MgB<sub>2</sub> nanoparticles (100-500 nm) to crystalline MgB<sub>2</sub> nanowires (10-20 nm diam) was developed. In this process, MgB<sub>2</sub> nanoparticle precursor was prepared through an in situ solid reaction of Mg metal and amorphous boron powder. After directly pyrolyzing the precursor via infrared irradiation at 900 °C in a high-purity argon atmosphere, uniform MgB<sub>2</sub> nanowires were produced at the edges of the precursor nanoparticles. Structural characterization and elemental composition analysis identified that the nanowires were made of MgB<sub>2</sub>, presumably incorporated or alloyed with some oxygen. Superconductivity of the samples was confirmed and it is indicated that the nanowires may have a transition temperature (T<sub>c</sub>) comparable with that of bulk MgB<sub>2</sub>.</p>
