The main ores of cobalt are cobaltite, ... Cobalt-57 is used as a source in Mössbauer spectroscopy and is one of several possible sources in X-ray fluorescence devices.
The main decay products before 59 Co are iron isotopes and the main products ... Cobalt-57 (57 Co or Co-57) is ... The 60 Co source is about 2 cm in diameter and as a ...
The compounds cobalt silicate and cobalt(II) aluminate (CoAl 2 O 4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy ...
The main advantage of 60 Co is that it is a high-intensity gamma-ray emitter with a relatively long half-life, 5.27 years, compared to other gamma ray sources of similar intensity. The β-decay energy is low and easily shielded; however, the gamma-ray emission lines have energies around 1.3 MeV, and are highly penetrating.
Its name stems from the contained element cobalt, whose name is attributed to the German term Kobold, referring to an "underground spirit" or "goblin". The notion of "bewitched" minerals stems from cobaltite and other cobalt ores withstanding the smelting methods of the medieval period, often producing foul-smelling, poisonous fumes in the process.
Around 75 per cent of the world’s cobalt is mined in the DRC -- and the world cannot get enough of it. The rare, silvery metal is an essential component to every lithium-ion rechargeable battery ...
[1] [2] Bacteria in the stomachs of ruminant animals convert cobalt salts into vitamin B 12, a compound which can only be produced by bacteria or archaea. A minimal presence of cobalt in soils therefore markedly improves the health of grazing animals, and an uptake of 0.20 mg/kg a day is recommended because they have no other source of vitamin ...
Eventually, a less costly pigment was developed from cobalt ores, giving the color its present-day name. Cosmic Cobalt has been a favorite color for artists of every era. Getty Images/Wikimedia ...
