THE SEPARATION OF THE FOUR PLATINUM GROUP METALS PALLADIUM, RHODIUM, IRIDIUM AND PLATINUM

Chemical vapor deposition of iridium, platinum, rhodium and palladium

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...

Platinum and the Metals of the Platinum Group.

WHAT promises to be the most complete and authoritative work on platinum and platinum deposits is about to be published in Geneva, Switzerland. The author, Louis Duparc, is professor of chemistry and petrology in the University of Geneva; the name of Marguerite N. Tikonovitch is announced as that of the associate author.' Professor Duparc has long been known as the writer of many papers on the ...

High Temperature Mechanical Properties of the Platinum Group Metals ELASTIC PROPERTIES OF PLATINUM, RHODIUM AND IRIDIUM AND THEIR ALLOYS AT HIGH TEMPERATURES

The platinum group metals are well suited for use at extremely high temperatures under mechanical loads and simultaneous corrosive attack. They have high melting points, excellent chemical stability and are highly resistant to oxidation. When using these materials in the design of components it is necessary to have data available on their elastic properties as a function of temperature. In this...

Biological availability of traffic-related platinum-group elements (palladium, platinum, and rhodium) and other metals to the zebra mussel (Dreissena polymorpha) in water containing road dust.

The uptake and bioaccumulation of 15 road dust metals by the zebra mussel (Dreissena polymorpha) were investigated in laboratory exposure studies with emphasis on the traffic-related platinum-group elements (PGEs) palladium (Pd), platinum (Pt), and rhodium (Rh). The biological availability of the metals may depend on water characteristics, so the mussels were maintained in two types of water: n...
