Ytterbium(III) sulphate octahydrate

Ytterbium is a chemical element with symbol Yb and atomic number 70. A rare earth metal, ytterbium is found in many minerals and its compounds have many applications. It is a soft, silvery, ductile metal that resists corrosion in air. The most important application of ytterbium is as the active component of the red phosphors in cathode ray tubes (CRTs), fluorescent lamps, television sets, computer screens, exit signs and other less common devices. Ytterbium-based red phosphors are brighter and last longer than those based on europium salts. Ytterbium sulphate octahydrate (YSO4·8H2O) is an acidic compound that can be used as a catalyst for organic reactions such as esterification or polymerization. It has been shown to catalyze the synthesis of particle-sized zirconia particles from zircon sand at high temperatures.
