Rh Rhodium

This voLume describes the buLk metaL rhodium and its aLLoys with arsenic to ruthenium in accordance with the GmeLin system. The first section, pages 1 through 37, covers in detaiL the foLlowing properties of the metal: CrystaLlographic properties; seLt-diffusion; me chanicaL properties (tensiLe properties, eLastic moduli, hardness, etc. ); thermaL properties (thermaL expansion, vapour pressure, specific heat, thermaL conductivity, etc. ); eLectricaL and magnetic properties (eLectric resistivity, superconductivity, HaLL effect, thermoeLectric force, magnetic susceptibiLity, etc. ); eLectrochemicaL behaviour and chemicaL reactions. A number of subject matters on metaLlic rhodium are aLready contained together with those of other pLatinum group metals in appropriate chapters of "PLatinum" SuppL. VoL. A 1, 1986. These incLude 1) preparation and eLectrodeposition, 2) zone-refining operations, and 3) chemicaL vapour deposition, sputtering, and thermaL evaporation. Likewise, "PLatinum" SuppL. VoL. 2, 1989, aL ready contains information on the 1) separa tion and properties of the Rh isotopes, 2) physicaL properties of the Rh atom and the atomic 2 ions Rh+ and Rh +, 3) the formation of Rh cLusters, and 4) the moLecuLar properties of Rh · 2 The second and major portion of this voLume, pp. 38 to 273, deaLs with the physicaL and chemicaL properties of rhodium aLloys. Phase diagrams of a Large number of binary and muLticomponent systems are treated in detaiL as weLL as the crystaLlographic and other properties of many intermetalLic compounds.
