This means it can measure the speed of chemical processes and track the movement of a substance through a cell or tissue, making it very useful in medicine and medical technology. A radioactive isotope of cobalt, cobalt-60, is used as a radioactive tracer. Cobalt blue (cobalt aluminate) is used to color glass, ink, varnish, paint, smalt and ceramics. Alloys are solid solutions consisting of two elements or more. It is also used often in magnetic alloys. It may lead to pernicious anemia while excessive levels of cobalt may cause death.Ĭobalt poisoning is a form of intoxication whereby cobalt reaches excessive levels in the body.Ĭobalt is used mostly as a metal in alloys with low wear-and-tear properties and high strength. Cobalt deficiency, which is a rate condition, can be potentially lethal. Its onset is associated with severe malnutrition, alcohol abuse, eating disorders, prolonged vomiting, or the effects of chemotherapy. The condition is also known as Korsakoff’s psychosis, Korsakoff’s dementia, and amnesic-confabulatory syndrome. Drastic deficiency of this enzyme results in Korsakoff’s syndrome, which strikes people with severe drinking problems. This element is the center of vitamin B12 (thiamine). Cobalt is also an important nutrient for bacteria, algae, and fungi. It is vital for their biological survival, health, and growth. The element is also produced as a byproduct of the extraction and refining of lead, silver, iron, copper, and nickel.Ĭobalt is an element, without which animals cannot function. Most cobalt that is mined in the world comes from Zambia and Congo. Today, this substance is derived from different metallic-luster ores, but it is mainly a by-product of copper and nickel extraction. The new metal, to which these ores were found to be reducible, came to be known as cobalt. This metal is also known as goblin ore (German) because of the blue color it produced and because it gives off poisonous fumes upon smelting. Eventually, it emerged that the metal bismuth had this function. It is used quite effectively as a blue pigment and has been used this way since antiquity for jewelry and other decorative items, to give glass a blue tinge, and more. When isolated, it is a silver-gray, lustrous, hard metal. Cobalt (symbol Co, number 27) is a chemical element occurring naturally only in a combined compound form.
