ABSTRACT:
Silicon nitride nanowhiskers predominantly having diameters substantially less than about 200 nm are disclosed. The nanowhiskers of Si.sub.3 N.sub.4 are produced by reacting gaseous SiO and N.sub.2 at elevated temperature and pressure in a reaction zone in the presence of a plurality of disperse carbon nanotubes having a diameter of from 3.5 to 70 nm.
