What lutetium is used for?
Lutetium is used in research. Its compounds are used as hosts for scintillators and X-ray phosphors, and the oxide is used in optical lenses. The element behaves as a typical rare earth, forming a series of compounds in oxidation state +3, such as lutetium sesquioxide, sulfate, and chloride.
Why is lutetium so expensive?
The most expensive natural element is francium, but it decays so quickly it can’t be collected to be sold. If you could buy it, you’d pay billions of dollars for 100 grams. If you order 100 grams of lutetium, it will cost about $10,000. Atoms of synthetic elements cost millions of dollars to produce.
Can you buy lutetium?
Lutetium Metal 99.9% Pure 1 Gram for Element Collection: Amazon.com: Industrial & Scientific.
Is lutetium poisonous or hazardous?
Health effects of lutetium Lutetium is mildly toxic by ingestion, but its insoluble salts are non-toxic. Like other rare-earth metals lutetium is regarded as having a low toxicity rating but it and its compounds should be handled with care.
What are 5 uses for lutetium?
Lutetium oxide is used to make catalysts for cracking hydrocarbons in the petrochemical industry. Lu is used in cancer therapy and because of its long half-life, 176Lu is used to date the age of meteorites. Lutetium oxyorthosilicate (LSO) is currently used in detectors in positron emission tomography (PET).
How much is lutetium worth?
Lutetium is worth approximately $10,000 per kilogram and for its high price it has found few commercial uses, although it has applications in the petroleum industry for petroleum cracking and has experimental uses in certain cancer treatments.
Where is lutetium commonly found?
Lutetium is never found in nature as the free element. Lutetium is found in the ores monazite sand [(Ce, La, etc.) PO4] and bastn°site [(Ce, La, etc.)(…Abundances of lutetium in various environments.

How long does francium last?
22 minutes
Characteristics. Francium is one of the most unstable of the naturally occurring elements: its longest-lived isotope, francium-223, has a half-life of only 22 minutes.
How much does lutetium cost?
Pure lutetium metal is very difficult to prepare. It is one of the rarest and most expensive of the rare earth metals with the price about US$10,000 per kilogram, or about one-fourth that of gold.

Where was indium found?
Indium was discovered in 1863 by Ferdinand Reich at the Freiberg School of Mines in Germany. Reich was investigating a sample of the mineral zinc blende (now known as sphalerite, ZnS) which he believed might contain the recently discovered element thallium.
What kind of scintillator is lutetium oxyorthosilicate ( CE )?
Lutetium Oxyorthosilicate – Lu₂SiO₅(Ce) – is a relatively dense scintillator with a fast decay time (40ns).It is similar in performance to BGO but with a higher light yield. HomeRadiation Detectors – ScintillatorRadiation Detectors – CZTRadiation DetectorsInterface ElectronicsPhotonicsContact
How is lutetium used in the real world?
Lutetium is extremely rare, but does have a few commercial uses. It is added as a dopant to garnets used in speciality lenses and magneto-optical memory storage devices. Cerium-doped lutetium oxyorthosilicate (LSO) is one of the most effective materials for detectors in positron emission tomography (PET) scanners.
Which is the insoluble form of lutetium oxide?
Lutetium oxide is available in powder and dense pellet form for such uses as optical coating and thin film applications. Oxides tend to be insoluble. Lutetium fluorides are another insoluble form for uses in which oxygen is undesirable such as metallurgy, chemical and physical vapor deposition and in some optical coatings.
Which is lutetium scintillator has a fast decay time?
Lutetium Oxyorthosilicate – Lu₂SiO₅ (Ce) – is a relatively dense scintillator with a fast decay time (40ns). It is similar in performance to BGO but with a higher light yield.
