ABSTRACT The preceramic polymer, polyhydridomethylsilazane, was synthesized and pyrolyzed at 1873 K in nitrogen atmosphere to prepare Si-N-C nanowires without using any catalysts. The diameters of the nanowires were from tens of nanometers to several microns, and the maximum length of the nanowires reached several hundred microns. The nanowires had no bulbs or droplets on the tips. However, two different bulbs with diameters of several microns were observed, and one bulb was covered by nanowires all around, while the other bulb had nanowires just covered on its handle.
