抄録

Silicon nitride nanorods were fabricated from Si, NaN<SUB>3</SUB>, and sulfur powder at 250 °C. XRD patterns show that the final product is mixed α- and β-Si<SUB>3</SUB>N<SUB>4</SUB>. SEM, TEM, and HRTEM images reveal that the product was composed of crystalline Si<SUB>3</SUB>N<SUB>4</SUB> nanorods with diameters in the range of 70–400 nm and lengths up to 3 μm. It is found that sulfur plays a crucial role in the low-temperature formation of Si<SUB>3</SUB>N<SUB>4</SUB> powders. Low reaction temperature and cheap raw materials make it possible for large scale synthesis of Si<SUB>3</SUB>N<SUB>4</SUB> nanomaterials.
