除了磷矿以外,地质工作者还在云南的寒武系地层里,找到了钒、镍、铀,和银矿。沾益的德泽,是一个含钒、镍、铀的矿床。钒是一种特殊的金属,被称为“化学面包”。如果说钢是虎,那么钒就是翼,钢含钒犹如虎添翼。只需在钢中加入百分之几的钒,就能使钢的弹性、强度大增,抗磨损和抗爆裂性极好,既耐高温又抗奇寒,难怪在汽车、航空、铁路、电子技术、国防
In addition to phosphate rock, geologists found vanadium, nickel, uranium and silver in the Cambrian strata of Yunnan. Deze Ze Zhanyi, is a vanadium, nickel, uranium deposit. Vanadium is a special kind of metal called “chemical bread”. If steel is a tiger, then vanadium is a wing, steel containing vanadium as a tiger wing. Just add a few percent vanadium in the steel, can make the steel flexibility, strength greatly increased, excellent wear resistance and burst resistance, both high temperature and resistance to cold, no wonder in the automotive, aviation, railways, electronics Technology, national defense
