How is praseodymium used?

Praseodymium is used in a variety of alloys. The high-strength alloy it forms with magnesium is used in aircraft engines. Mischmetal is an alloy containing about 5% praseodymium and is used to make flints for cigarette lighters. Praseodymium is also used in alloys for permanent magnets.

How is gadolinium used in everyday life?

Gadolinium is used to make gadolinium yttrium garnets which have microwave applications. Gadolinium compounds are used as green phosphors in color television picture tubes. Because of its magnetic properties, gadolinium is also used in intravenous radiocontrast agents in magnetic resonance imaging (MRI).

What type of mine or process is used for europium?

Although europium is found in high quantities in minerals such as calcium speldstars (calcium aluminium silicates), this is not used as a commercial source, and instead it is mined from the rare earth minerals, monazite and bastnasite, which are sources for all the lanthanoid elements.

What are uses for scandium?

Scandium is used in aluminum-scandium alloys for aerospace industry components and for sports equipment such as bicycle frames, fishing rods, golf iron shafts and baseball bats. Scandium iodide is used in mercury vapor lamps, which are used to replicate sunlight in studios for the film and television industry.

What is the 65th element?

Terbium, element number 65, is no different and lies in the middle of the lanthanide series in between gadolinium and dysprosium. It is one of the rarer rare earth elements, although it is still twice as common as silver in the Earth’s crust.

Why gadolinium is used in MRI?

Gadolinium contrast medium is used in about 1 in 3 of MRI scans to improve the clarity of the images or pictures of your body’s internal structures. This improves the diagnostic accuracy of the MRI scan. For example, it improves the visibility of inflammation, tumours, blood vessels and, for some organs, blood supply.
