The Discovery of Tantalum Metal
In the mid-17th century, a heavy black mineral (the density of tantalum was 16.68g/cm cubed) found in North America was sent to the British Museum for storage. About 150 years later, in 1801, the British chemist, Charles hatchet accepted the task of analyzing this mineral from the British Museum. Then a new element was discovered and called Columbium, which was to commemorate the first place where the mineral was discovered -- Colombia.
Tantalum is named for Tantalus. In 1802, Swedish chemist A.G.Ekaberg analyzed a mineral (niobium-tantalum) in Scandinavia, and he made its acid produce fluorinated salts, then recrystallized, and discovered new elements. He named the element Tantalum (Tantalum), referring to the name of Tantalus, the son of Zeus god in Greek mythology.
Because colum and tantalum are very similar, they were once thought to be the same element. In 1809, the British chemist William Hyde Wollaston compared the oxide of tantalum and colum, although different densities were obtained, he thought they were the same substance.
By 1844, the German chemist, Heinrich Rose, rejected the conclusion that tantalum and columbium were the same elements, and they were identified by chemical methods as two distinct elements. He named the two elements "Niobium" and " Pelopium ", the daughter Niobe of Tantalus and his son Pelopium in Greek mythology.
In 1864, Christian Wilhelm Blomstrand and Louis Joseph Troost made it clear that tantalum and niobium were two different chemical elements and determined the chemical formulas of some related compounds.
In the same year, DE Mariia heated the tantalum chloride in the hydrogen environment to make the tantalum metal for the first time. In the early stage, the tantalum metal contains more impurities. Werner von Bolton first made pure tantalum metal in 1903.
It was first used by scientists to extract tantalum from niobium. This method was discovered in 1866 by DE Mariya. Today, the scientists used a solvent extraction method for tantalum containing fluoride.
