摘要：

Recently nanowires, especially silicon nitride (Si3N4), have been the emphasis of recent researches, due to their potential application. In this work, the authors developed a catalyst-free method to prepare Si3N4 nanowires by heating the mixture of Si powder and SiO2 sol, coupled with carbon felt at 1500 degrees C in a N-2 atmosphere. The nanowires were composed of alpha-Si3N4 and beta-Si3N4, with lengths of 1-2 mm and diameters of 1.5 mu m. Meanwhile, the vapour-solid mechanism was employed to interpret the nanowires growth, and this method may be applied to synthesise other long nanowires.
