Synthesis of Titanium Nitride Powder by Spark Discharge Process in Liquid Nitrogen

Synthesis of Nanocrystalline Titanium Carbide by Spark Erosion

Interest in nanocrystaJline ceramic powders is due to their attractive processing and mechanical properties. The disadvantages of conventional ceramics, such as large internal flaws, negligible ductility, hightemperature processing, can possibly be eliminated or minimized by starting with finegrained powders. A previous study on the sinterability of nanocrystalline ceramic powders showed that h...

Direct synthesis of titanium nitride by laser-plasma

The Synthesis of Carbon Nano Tubes by Arc Discharge Method in Liquid media

In this investigation a simplified arc discharge apparatus was used to synthesize mullti-wall carbon nanotubes. Because of not requiring vacuum equipment, heat exchange system, active or inert gases, this method is found to be cheaper and simpler than traditional arc discharge in gas environment. Using this method, CNTs are produced by performing an arc discharge between two graphite electrodes...

Titanium Nitride Thin Films by the Electron Shower Process

Titanium nitride (TiN), a stable compound with the NaCl structure, has a wide range of properties which find applications in cutting tools, wear resistant parts, semiconductor metallization, and the jewelry industry. However, there are problems with preparing highly adhesive thin films which maintain good properties. Thin films of titanium nitride have been prepared by the Electron Shower (ES) ...

Aerosol Generation by Spark Discharge*

An aerosol generator producing particles of any desired mobility, equivalent radius, and conducting material has been developed. Particles are formed by electrode atomization in a spark discharge. A high yield of charged particles enables generation of high concentration (> 10’ cmm3) monodisperse aerosols using electrostatic classification. In order to obtain nonagglomerated particles, the aero...
