Abstract(in English) The characteristic of an arc discharge phenomenon is influenced by many external conditions, such as gas pressure, gases, and circuit current. After taking these external conditions into consideration, the characteristic of an arc discharge phenomenon can describe from the thermodynamic and transport properties (electrical conductivity, viscosity, thermal conductivity, etc.). In this report, we calculated thermodynamic and transport properties (electrical conductivity and specific heat) of arc occurring between Ag and Ag/SnO_2 contact pairs in Ar atmosphere. The calculation result was compared with the particle compositions, and the thermodynamic and transport properties in air atmosphere. The following results are obtained. Focus on metallic particles and electron; the particle compositions are independent of the atmosphere gas. The electrical conductivity is independent of the atmosphere gas and the contact materials. The specific heat at constant pressure in Ar atmosphere, the value is smaller as compared with the case of air atmosphere. Moreover, the relative maximum temperature is different.
