The thermodynamic and transport properties of an argon‐alumina mixture were calculated assuming local thermal equilibrium for a temperature range of 4000 to 20,000 K with a pressure of 10 5 Pa. The main effects of alumina injection into argon are summarized below. Specific enthalpy and specific heat increase due to dissociation of AlO molecules and ionization of Al and O atoms. Electrical conductivity dramatically increases below 15,000 K due to low ionization energy of Al atoms. Thermal conductivity increases below 11,000 K due to dissociation of AlO molecules and of ionization of Al atoms. Viscosity decreases below 14,000 K due to relatively large cross section of Al + ions. © 2002 Wiley Periodicals, Inc.
