稀土是元素周期表中15个镧系元系再加上钪和钇共计17个金属元素的总称,常用R或RE表示。它们的名称和化学符号是钪(Sc)、钇(Y)、镧(La)、铈(Ce)、镨(Pr)、钕(Nd)、钷(Pm)、钐(Sm)、铕(Eu)、钆(Gd)、铽(Tb)、镝(Dy)、钬(Ho)、铒(Er)、铥(Tm)、镱(Yb)、镥(Lu)。一、“稀土”资源的战略价值稀土的用途十分广泛。只要在一些传统产品中加入适量的稀土,就会产生许多神奇的效果。目前,稀土已广泛应用于冶金、石油、化工、轻纺、医药、农业等数十个行业。稀土
Rare earth is the periodic table of 15 lanthanides coupled with scandium and yttrium in total a total of 17 metal elements, commonly used R or RE said. Their names and chemical symbols are Sc, Y, La, Ce, Pr, Nd, Sm, Sm, Eu Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu. First, the “rare earth” strategic value of resources The use of rare earth is very wide. As long as some traditional products in the right amount of rare earth, it will have a lot of magical effects. At present, rare earth has been widely used in metallurgy, petroleum, chemical, textile, medicine, agriculture and other dozens of industries. Rare earth
