Ytterbium is a silvery, soft, malleable, and ductile metal with a lustrous metallic shine.It is slightly reactive in air or water at room temperatures. Ytterbium is located next to lastof the rare-earths in the lanthanide series. It slowly oxidizes as it reacts with oxygen in theatmosphere, forming a somewhat duller coating. Ytterbium was the first rare-earth to bediscovered by Carl Gustof Mosander in 1843. More of it exists in the Earth’s crust than oncewas believed.It was often confused with other rare-earths and was known by two other names, aldebaraniumand cassiopeium. Ytterbium’s melting point is 819°C, its boiling point is 1,196°C, andits density is 6.9654g/cm3.
Isotopes
There are a total of 37 isotopes of ytterbium. Seven of these are stable, andthey make up all of the natural ytterbium found on Earth. One of these isotopes (Yb-176) has such a long half-life (1.6×10+17years) that it contributes 12.76% of the naturalytterbium existing on Earth, and thus it is considered stable. All the other 30 isotopes areartificially radioactive and produced by nuclear fission in nuclear reactors with half-livesranging from a fraction of a second to 32 days.Origin of Name
Ytterbium is named for the Ytterby quarry located in Sweden.출처
Ytterbium is the 45th most abundant element, and it ranks 10th in abundance (2.7 ppm)among the 17 rare-earths found in the Earth’s crust.It is found in ores along with other rare-earths that were first found in the Ytterby quarryof Sweden. These ores are xenotime, euxenite, gadolinite, and monazite. Monazite river sand is the main source of ytterbium, which is found in India and Brazil and the beaches of Florida.Ytterbium is also found as a decay product of the fission reaction in nuclear reactors.
Characteristics
In the past there was some confusion about the rare-earths because they are not really earthsat all, but rather binary compounds of oxides of metals. Compounding the confusion was thefact that they were always found combined with several other rare-earths.The salts of ytterbium are paramagnetic, which exhibit weaker magnetic fields than do ironmagnets.
용도
Ytterbium is being applied to numerous fiber amplifier and fiber optic technologies and in various lasing applications.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.
Ytterbium can also be used as a dopant to help improve the grain refinement, strength, and other mechanical properties of stainless steel. Some Ytterbium alloys have rarely been used in dentistry.
It is also used as in thermal barrier system bond coatings on nickel, iron and other transitional metal alloy substrates.
Ytterbium Metal, is being applied in improving the grain refinement, strength, and other mechanical properties of stainless steel and alloys. The 169Yb has been used as a radiation source in portable X-ray machines.169Yb is also used in nuclear medicine. Ytterbium can also be used as a dopant to help improve the grain refinement, strength, and other mechanical properties of stainless steel. Some ytterbium alloys have rarely been used in dentistry.
Ytterbium Metal can be further processed to various shapes of ingots, pieces, wires, foils, slabs, rods, discs and powder.
정의
A soft malleable silvery element having two allotropes and belonging to the lanthanoid series of metals. It occurs in association with other lanthanoids. Ytterbium has been used to improve the mechanical properties of steel. Symbol: Yb; m.p. 824°C; b.p. 1193°C; r.d. 6.965 (20°C); p.n. 70; r.a.m. 173.04.위험도
Ytterbium dust and powder can explode and may be toxic if inhaled. The compound.ytterbium arsenate is a poison.Safety Profile
As a lanthanon it maj7 have an anticoagulant action on blood. Questionable carcinogen with experimental tumorigenic data. Flammable in the form of dust when reacted with air, halogens. See also LANTHANUM and RARE EARTHS.이터븀(이테르븀) 준비 용품 및 원자재
