Rhodium
MATERIAL OVERVIEW
Characteristics: White solid of platinum group. Insoluble in acids and aqua regia, soluble in fused potassium bisulfate. Harder and higher-melting than platinum or palladium. Rhodium has the highest electrical and thermal conductivity of the platinum group. High surface reflectivity. A strong complexing agent.
Hazards: Flammable in powder form. Tolerance (fumes and dusts) 0.1 mg/m3 of air; (soluble salts, as Rh) 00.001 mg/m3 of air.
