AREAS OF APPLICATION

Its main application is in the glass industry, where it is used to produce infrared-absorbing glass. As a laser, the element is also used in nuclear medicine, and in dentistry it is used to produce all-ceramics. In nuclear technology, the rare earth element is used as a neutron absorber. It is also used in catalytic converters.

• solid-state laser;
• as beta emitters in nuclear medicine (treatment of joint diseases);
• optical amplifiers;
• Production of catalysts;
• polishing of glass.

The extraction of erbium

After a complex separation of the other erbium companions, the oxide is reacted with hydrogen fluoride to form erbium fluoride. Subsequently, it is reduced with calcium to form calcium fluoride to the metallic erbium. Separation of remaining calcium residues and impurities takes place in an additional remelting in vacuum.

Special features

The silvery-white shining rare earth metal is malleable, but also rather brittle. In air, erbium tarnishes to gray, but is then quite stable. At higher temperatures it burns to the sesquioxide Er2O3. With water it reacts with hydrogen evolution to hydroxide. In mineral acids it dissolves to form hydrogen.

Erbium Usage

Erbium 3+ ions have optical properties that account for most applications of the element. Erbium-doped glasses and crystals are used as laser gain media, optical fibers, and amplifiers in fiber optic communication systems. Erbium lasers are also widely used in medicine, dermatology and dentistry, and stronger erbium-ytterbium lasers are used in metal cutting and welding. The same distinct absorption and emission spectra that make erbium useful for functional optical applications result in the distinct pink coloration of erbium 3+ compounds, so erbium can also be used aesthetically as a dye for glasses, ceramics, and zirconia. In addition to its optical properties, erbium is useful for its ability to readily absorb free neutrons, making it suitable for use in control rods in nuclear reactors. In addition, erbium alloys are used in cryocoolers for use at liquid helium temperatures because of their high specific heat capacity. Erbium-doped optical fibers are used for optical amplifiers capable of amplifying a light signal without first converting it to an electrical signal. Gold as a host material doped with a few hundred ppm of erbium is used as a sensing material of magnetic calorimeters for high-resolution particle detection in physics and engineering. Erbium is used alongside other rare-earth elements such as neodymium or holmium for dot Fiber optics through erbium ization of laser crystals in solid-state lasers. The Er:YAG laser is mainly used in human medicine. It has a wavelength of 2940 nm and thus an extremely high absorption in tissue water of about 12000 per cm. It causes abrupt vaporization and thus photoablation of tissue in thin layers. It is suitable for ablation of a wide range of benign skin lesions. A biopsy is prescribed beforehand to rule out malignancy. Ablated melanomas, for example, are strongly suspected of metastasizing via the bloodstream due to cells detached during ablation. Similarly, it is used in the processing of hard tissues such as bone, enamel and dentin (healthy and carious). Another erbium-based laser is the Er,Cr:YSGG laser, which has a slightly shorter wavelength of 2790 nm but serves the same medical or dental indications.
