What is cobalt?
cobalt is a metal chemical element that is relatively hard and brittle in its pure form. It is used industrially in many ways and is also refined to produce salts and isotopes that have other practical applications. In addition to being an important part of many products, cobalt is also a decisive trace element necessary for human well -being. The gray, slightly matt element is rarely available in pure form, but can be found in many alloys. The name of the metal is derived from the German word for "goblin", a link to the elves that allegedly used it to replace valuable silver ores. The element was also considered a goblin because it tended to often appear with Arsen, a highly toxic element. When melting, arsenic fumes will be released and threatened the health of workers.
One of the most famous uses cobalsates for the blue dye extracted from its salts. This dye has been used for thousands of years, with samples appear in Egyptian and Greek tombs. The metal itself is often used in alloys to createthings such as magnets or metals that can withstand high temperatures. These high temperature alloys are used in things such as current engines. In addition, cobalt can be divided into radioactive isotopes that have a number of uses in medicine, industry and research.
usually cobalt is located near nickel, lead, copper and silver ores. The metal appears in the form of ore, usually strongly mixed with other materials, so it is necessary to improve it. Like many metals, ferromagnetic properties have and can be spontaneously magnetized or hold a magnetic charge for a long time. This feature makes cobalt a popular choice in alloys used to produce rare soil magnets.
As with some of the trace elements, cobalt can be dangerous for human health, if consumed in large quantities. People usually receive all the minerals they need by making it a balanced and healthy diet,Although some animals may require accessories. In large doses, cobalt can damage the heart and lungs. Radioactive isotopes used in various medical treatments can also be very harmful and are carefully controlled as a result.
