About Cobalt (pronounced koh-bawlt) The 27 elements in the periodic table of elements are \"silver- White metal elements, with a touch of pink \", are solid in a closely stacked hexagonal structure at room temperature. This transition metal has the following physical properties: the atomic weight is 58. 93 grams, density 8. 86 grams per cubic centimeter, melting point of 1495 degrees Celsius, boiling point of 2927 degrees Celsius. Cobalt has only one stable isotope that naturally exists and is usually obtained as a by-product when nickel, silver, lead, copper and iron are mined and refined. It can be found in cobalt, glass, lithium and smaltite mines. But what is the real meaning of all these scientific terms? Here are some interesting facts and common applications for this element: 1. According to the World English Dictionary, cobalt comes from the German word \"Kobalt\", which is derived from the high word \"kobolt\" in German, meaning \"Goblin \", because the miners think that \"the malicious essence put it in the silver ore. ”2. Swedish chemist George Brandt discovered cobalt in 1739, when he tried to counter the contemporary view that the element bismouth had the ability to color the glass blue. 3. Alnico alloys ( Aluminum, cobalt and nickel) Used to make powerful permanent magnets. 4. Si Tai Li alloy (Chromium, cobalt, tungsten) High for production-speed, high- Due to the high melting point and strength of cobalt at high temperature, the temperature cutting tool. 5. Other cobalt-containing alloys are used to produce gas turbines and jet engines. 6. Radioisotopes of cobalt60 (half-life of 5. 27 years) Is the source of gamma rays. It can be used for some forms of cancer treatment and medical tracking. 7. Compounds containing cobalt have been used as dyes and colorants. The common names of some compounds are: cerulum, cobalt blue, Cobalt green, cobalt yellow and new blue. 8. Cobalt is part of vitamin B12 ( Also called cobalt amine) The importance of nutrition. According to the Office of Dietary Supplements, this is a natural water \"The soluble vitamins needed for proper red blood cell formation, neurological function, and DNA synthesis. The lack of this mineral in the daily diet can lead to \"anemia, fatigue, weakness, constipation, loss of appetite and weight loss in giant young cells \". ”9. Canada, Morocco and Zairian are important sources of cobalt. The U. S. Geological Survey report cobalt- North-Central Pacific near the Hawaiian Islands and other affluent parts of the United StatesS. Territories. 10. Lithium ion, nickel- The cadmium and nickel metal hydrogen batteries are made of a large amount of cobalt. 11. The use of cobalt in rechargeable batteries increased from 22% in 2006 to 25% in 2007, the fastest increase in metal usage. 12. Global cobalt consumption in 1995 was 24,000 tons, up to 60,800 tons in 2008. That is a 7. In 13 years, it has increased by 4%. If demand continues, it is expected that this number will increase to 72,500 tons in 2011.
