Abstract: | A new method to fabricate nanomaterials by using Impulse Plasma in Liquid is presented. Impulse plasma appears from inter-electrode
space break-down in high potential difference between two electrodes submerged into a dielectric liquid, while the power supply
is relatively small that is insufficient to excite an arc discharge. By changing the dielectric liquid, we can obtain metallic
particles, oxides, carbides. This method does not require vacuum chamber and high energy, thus, can provide economical preparation
of various types of nanomaterials. Nanocrystalline powder of titanium oxide was prepared using purified water as a dielectric
liquid. Metallic nanoparticles of ytterbium, silver and copper were also prepared by the impulse plasma between a pair of
the same material electrodes submerged in styrene. In addition, fullerene C60 was synthesized by the impulse plasma in toluene. Nanoparticles of TiC, WC, TaC were also synthesized by the impulse plasma
in styrene. |
