Studies on iridium and platinum determination in metallic rhodium by NAA and CPAA

Vapor Pressures of Platinum , Iridium , and Rhodium

Systematic measurements of the vapor pressure of iridium and rhodium over a wide temperatme range have not been published previously. A summary of previous estimates or observations of their normal boiling points and values of their heats of sublimation, f:..H ~ (298), is given in table l. The vapor pressure of platinum was calculated by Langmuir and .Mackay from measurements of the rate of sub...
