  • Title: Synthesis of silicon nitride nanowires by the pyrolysis of perhydropolysilazane.
    Author: Qi GJ, Zhang CR, Hu HF.
    Journal: J Nanosci Nanotechnol; 2006 May; 6(5):1486-8. PubMed ID: 16792386.
    Abstract:
    Silicon nitride nanowires synthesized by the pyrolysis of perhydropolysilazane without using any catalysts are reported. After pyrolysis at 1073 K in N2/NH3 atmosphere, the synthetic nanowires are discrete and curly with diameters about tens of nanometers and lengths of hundreds of nanometers. While after post-treatment at 1873 K in N2 atmosphere, the nanowires are continuous and randomly distributed with diameters about tens of nanometers and several microns in length. There are no bulbs or droplets on the tips of the nanowires, and two gas-solid mechanisms are proposed to explain their growth.
