FEASIBILITY STUDIES ON GENERATION-, MEASUREMENT- AND APPLICATION- TECHNIQUES OF ULTRA-HIGH TEMPERATURE FIELDS BY ARC-DISCHARGE. (PART 2: ANALYSIS OF ARC-PLASMA FIELDS).

The analyses on arc-plasma fields are surveyed in this report. The first part describes the mechanism of the arc discharge. The phenomenon of the discharge in the neighborhood of cathodes is complicated and not still understood completely. The second part gives the detailed descriptions of the analytical approaches to the plasma jet fields generated by the arc discharge, working gas and plasma torch. These plasma fields play an important role to handle the coal gasification, plasma sprayed coating, and the synthesis of new ceramics and of ultra-fine particles. Finally, it is discussed how the particles inserted into the plasma field have the influences on that field.
