SILICON NITRIDE NANOWHISKERS AND METHOD OF MAKING SAME

摘要

Silicon nitride nanowhiskers predominantly having diameters substantially less than about 200 nm are disclosed. The nanowhiskers of Si3N4 are produced by reacting gaseous SiO and N2 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.
