你對鎳有咩認識? 如果你同大部分人一樣, 答案唔多. 然而, 知道呢個: 氮氣係用喺各種嘢入面, 由低過敏首飾到超導磁石. 你甚至會喺一啲噴射引擎入面搵到鎳.
Niobium Characteristics
Niobium is a shiny, 白色金屬，可能會變成藍色嘅色調, green or yellow when exposed to air. With the atomic number of 41 and the symbol Nb, niobium has an atomic weight of 92.906 and a density of 8.57 grams per cubic centimeter. At room temperature it’s solid. Niobium’s melting point is 4,491 degrees Fahrenheit and its boiling point is 8,571 F度.
Niobium History
Niobium used to be called columbium in the U.S. for some 100 年, whereas it was niobium in Europe. It has a complicated history, but suffice it to say that niobium was pretty much “figured out” in the mid-1800s. Around 1950, the International Union of Pure and Applied Chemistry officially adopted niobium as the element’s name, in deference to European usage. 話雖如此, you might still find some who refer to it as columbium!
Where Niobium is Found and Utilized
In nature, niobium is almost always found with tantalum. Today it’s found and mined in Brazil and Canada, with enough to last for probably the next five centuries according to experts.
Where is niobium most utilized? That would be in the steel industry. It’s used to create high-strength, low-alloy steels. Niobium is used to increase toughness as well as corrosion resistance.
最後., niobium is known as one of the five refractory metals, all of which have very high resistance to heat and wear.
