Charles Hatchett – discoverer of niobium element

charles-hatchettCharles Hatchett was an English chemist born on January 02, 1765 – died on March 10, 1847. Hatchett was well known for his discovery of niobium periodic table element. Niobium is a soft, grey, ductile transition metal, which is often found in the pyrochlore mineral, the main commercial source for niobium, and columbite. Niobium becomes a superconductor at cryogenic temperatures. Niobium is slightly less electropositive and more compact than its predecessor. Read More
