Vanadium

钒

Vanadium is classified as a transition metal and is the most important in its group (called the Vanadium group). It finds extensive use in the manufacture of special steels with exceptional strength and toughness. One use is for the manufacture of automobile crankshafts.

钒被归类为过渡金属，并且是其组（称为钒组）中最重要的元素。它在制造具有优异强度和韧性的特种钢中得到广泛应用。一种用途是用于制造汽车曲轴。

It occurs naturally in the mineral vanadinite. It is also found in the silicate mineral cavansite. An oxide with zinc and lead is descloizite. Vanadium appears with uranium and lead in Francevillite. An oxide of copper with vanadium is volborthite. An oxide of vanadium with zinc, copper and lead is mottramite.

它自然存在于钒华石矿物中。它也出现在硅酸盐矿物卡瓦斯石中。含锌和铅的氧化物是descloizite。钒与铀和铅共同存在于法国石中。含钒的铜氧化物是volborthite。含钒、锌、铜和铅的氧化物是mottramite。
