锆属元素周期表IVB族元素,元素符号Zr,原子序数40,原子量91.22,密度6.52g/cm3,熔点1855℃。锆在地壳中的丰度约为0.025%,超过镍、铜、锡、铅等常用金属。由于提炼和加工困难,锆被划归稀有金属。锆是德国化学家克拉普洛特于1789年发现的元素,经过150多年的漫长岁月,直
Group IVB elements of the zirconium periodic table, elemental symbols Zr, atomic number 40, atomic weight 91.22, density 6.52 g / cm3, melting point 1855 ° C. The abundance of zirconium in the crust is about 0.025%, more than nickel, copper, tin, lead and other commonly used metals. Zirconium is classified as a rare metal due to difficulties in refining and processing. Zirconium is the element discovered by German chemist Kraplott in 1789. After more than 150 years of long years, zirconium
