Equilibrium composition of high-temperature argon contaminated with fly-ash was theoretically obtained in consideration of phase transformation of fly-ash including some metals : Na, Mg, Al, K, Ca and Fe. The calculation was performed in a temperature range from 300 to 30000 K at a pressure of 0.1 MPa. The result revealed that as the temperature decreases, first, iron and aluminum in gas phase transform into condensed phase around 2000 K and that further reduction in the temperature causes calcium, magnesium, sodium and kalium to transform into condensed phase. From the obtained equilibrium composition, thermodynamic and transport properties were also derived.
