Abstract A metal two-bulb apparatus for the measurement of the thermal diffusion factor, α T , especially at temperatures below room temperature, has been designed and constructed. The results for the argon-krypton system are reported, and these cover five mixture compositions (25, 40, 50, 60, and 75% of krypton). The top bulb is maintained at 293.2 K, while the temperature of the lower bulb is varied in the range 102–250 K. The measured α T values are estimated to be accurate within ±4%. The positive minimum in the present α T values is less pronounced than that reported by some other workers, and this is attributed to the operating conditions and to the apparatus geometry.
