Thermal conductivity of mixtures of argon‐helium, argon‐nitrogen, and argon‐neon

Abstract A secondary concentric cylinders cell was used to measure the thermal conductivity of binary mixtures of argon‐nitrogen, argon‐helium, and argon‐neon approximately 20, 40, 60, and 80 vol. % at 75°C, and pressures to 2,800 atm. Measurements were made also on the pure gases argon and nitrogen.
