Production; thermocouple-sensing elements for high temperatures, 1570°K (Pt- Rh. Up to 2570°K (Ir- Rh.
Rhodium Production
http://rhodium.atomistry.com/production.html
Is concentrated in mother solutions after platinum xD0 xB8 palladium separation from hydrochloric solutions appeared after platinum processing or Cu and nickel electrochemical refining. Contaminating metals are extracted by nitration, after which rhodium chloride. Complexes pass into Na. And precipitated by NH. It is dissolved by heating with hydrochloric acid and reduced by formic acid; heating in hydrogen at 1000°C yields rhodium sponge. Refining) is processed by chlorine treatment of rhodium sponge.
Rhodium Ionization Energy
http://rhodium.atomistry.com/energy.html
The Rhodium Ionization Energy. Is the energy required to remove from atom one mole of electrons with subsequent production of positively charged ion of Rhodium. This process can be repeated many times, but the energy cost is increased dramatically. The general equation for the Rhodium is:. 720 kJ/mol = 172.25 Kcal/mol. 1744 kJ/mol = 417.22 Kcal/mol. 2997 kJ/mol = 716.99 Kcal/mol. 4400 kJ/mol = 1052.63 Kcal/mol. 6500 kJ/mol = 1555.02 Kcal/mol. 8200 kJ/mol = 1961.72 Kcal/mol.
Chemical Properties of Rhodium
http://rhodium.atomistry.com/chemical_properties.html
Chemical Properties of Rhodium. Appears, from more recent research, to be an ill-defined mixture of metallic rhodium and its sesquioxide. The reaction is noticeable at 600 C., and increases in velocity with rise of temperature. At ordinary temperatures oxygen is without action upon rhodium. Chlorine attacks the finely divided metal, the reaction beginning at 250 C., yielding the trichloride, Rh. Which at high temperatures undergoes partial dissociation.
Physical Properties of Rhodium
http://rhodium.atomistry.com/physical_properties.html
Physical Properties of Rhodium. Physical properties of Rhodium are related with its melat nature. Rhodium is a white metal resembling aluminium in appearance. Its density has been variously given in values ranging from 11 to 12.1. Its mean specific heat is 0.058, and its coefficient of linear expansion with rise of temperature is 0.04058.

Element Rhodium, Rh, Transition Metal
Element Rhodium, Rh, Transition Metal. Was discovered in 1803 by William Hyde Wollaston, soon after his discovery of palladium. Wollaston dissolved raw platinum in aqua regia. The acid surplus was neutralized by caustic soda. He then precipitated the platinum by adding ammonium chloride, NH. Cl; palladium was removed as palladium cyanide after treating the solution with mercuric cyanide. The material that remained was a red powder double ( rhodium. Chloride. Rhodium metal. Crustal abundance is 1x10.
