| Research Abstract |
The behavior of bubbles and discharge characteristics generated by a high frequency in-liquid plasma was investigated in liquids under higher pressure than atmospheric pressure. The degree of ionization of the in-liquid plasma is approximately 0. 1% at 0. 4MPa, as estimated from the electron density, however, the electrons remain in the plasma reaction field within the bubbles where temperatures of several thousand degrees are created as a result of the harsh vibration by the high frequencies. The in-liquid plasma maintains a high superheated because a boiling phenomenon in the in-liquid plasma uses the plasma itself as a heating source. Metric nanoparticles can be synthesized by feeding a metallic rod a source material into in-liquid plasma.
