    Physical PropertiesGrayish-white metal; face-centered cubic crystals; density 12.41 g/cm3; hardness, annealed 100-120 Vickers units; melts at 1,964°C; vaporizes at 3,695°C; electrical resistivity 4.33 microhm–cm at 0°C; tensile strength, annealed 50 tons/in2; Young’s modulus, annealed 2.3×104 tons/in2; magnetic susceptibility 0.99×10–6 cm3/g; thermal neutron absorption cross section 156 barns; insoluble in water; soluble in concentrated sulfuric or hydrochloric acid under boiling conditions; the metal in massive form is slightly soluble in aqua regia, but in small quantities or in thin plates it partially dissolves in aqua regia; forms solid solutions with platinum, palladium and iridium.
    ReactionsAt ordinary temperatures rhodium is stable in air. When heated above 600°C, it oxidizes to Rh2O3, forming a dark oxide coating on its surface. The gray crystalline sesquioxide has a corundom-like crystal structure. The sesquioxide, Rh2O3 , decomposes back to its elements when heated above 1,100°C. However, on further heating the metal starts to lose its weight similar to platinum, probably due to loss of its volatile oxide RhO2 dissolved in the metal. The molten metal readily absorbs gaseous oxygen.
    The metal in powder form absorbs hydrogen when heated. When heated with carbon monoxide under pressure rhodium forms carbonyl, Rh4(CO)12. The metal combines with halogens at elevated temperatures. When heated with fluorine at 500 to 600°C, it forms a trifluoride, RhF3, a red rhombohedral crystalline powder insoluble in water, dilute acids, or alkalis. Also, a blue tetrafluoride, RhF4, is formed as a minor product. When heated with chlorine gas above 250°C, the brown-red trichloride, RhCl3, forms. It is hygroscopic, decomposing at 450°C.
    Rhodium is attacked by fused caustic soda or caustic potash. Also, fused sodium or potassium cyanide and sodium bisulfate attack the metal.

    Reactive Group:

    Metals, Less Reactive

    Reactivity Alerts:

    Highly Flammable

    Reactivity Profile:

    RHODIUM FUME is flammable. Acts as a reducing agent. Reacts violently with BrF5, ClF3 and OF2. Reacts with fluorine, with chlorine (when heated), hydrogen peroxide, sulfur dioxide (when heated), and nitrogen dioxide. Also incompatible with Zn. May catalyze reactions between other materials. Reactivity may be altered by the presence of insoluble rhodium compounds depending on the specific compounds and their proportions in the mixture.
