Ytterbium

Description

Ytterbium is being applied to numerous fiber amplifier and fiber optic technologies and in various lasing applications. It has a single dominant absorption band at 985 in the infrared range, making it useful in silicon photocells to directly convert radiant energy to electricity. Ytterbium metal increases its electrical resistance when subjected to very high stresses.

This property is used in stress gauges for monitoring ground deformations from earthquakes and nuclear explosions. It is also used in thermal barrier system bond coatings on nickel, iron, and other transitional metal alloy substrates.

Ytterbium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and componds as submicron and nanopowder.
