An analysis of the effects of vapor diffusion in ruthenium-chlorine system transpiration experiments was used for interpreting the results of experiments in which the effects of flow rate on the quantity of vapor transported were studied. Data are presented graphically for the against the vapor transport. Vapor-pressure studies in the ruthenium-chlorine system are reported, and data at 600 to 1000 deg C are given. Results show that the chlorine effect is due to RuCl/sub 4/ rather than RuCl/sub 3/ (g) as originally assumed. RuCl/sub 3/ (g) apparently becomes important at higher temperatures. Data and discussions related to pressure dependence of the solid-vapor equilibrium are presented for the RuCl/syb 2/ system. Also, data on the temperature dependence for the equilibrium of the RuCl/sub 3/-RuCl/sub 4/ gaseous and solid systems are included. Thermodynamic properties of gaseous ruthenium chlorides are also listed. Data on the dissociation of rhodium chloride were obtained, and vapor pressures of the rhodium-chlorine system at 800 and 900 deg C are tabulated. Palladium rhloride was also studied and data on the dissociation pressure at 700 to 850 deg C are given along with data on effects of rhlorine in the system Cl-Pd on vapor pressure. The dissociation of RuCl/sub 3/ was determined at 650 to 839 deg C by static and dynamic methods. (For preceding period see GA-461.) (J.R.D.)
