稀有元素锆,是德国化学家克拉普鲁特在1789年首先发现的。直到1914年,人们才等一次制得金属锆。纯锆是银灰色金属,富有延展性,只要稍有一点杂质,就会变得很脆;锆是一种高温难熔的金属,熔点高达1930℃;金属锆粉呈黑色,极易自燃,燃烧时发出强烈的光亮;锆耐腐蚀;机械性能好,易于加工。锆在地壳中没有单独存在的矿床,常与钛铁、独居石等矿共存,因此提取困难。近二十年,由于科学技术的发展,锆在原子能工业及宇宙火箭的生产上崭露头角,受到 Rare elemental zirconium, first discovered by German chemist Klaput in 1789. It was not until 1914 that people prepared the metal zirconium once. Pure zirconium is a silver-gray metal, ductile, as long as a little impurity, it will become very brittle; zirconium is a high temperature refractory metal, melting point up to 1930 ℃; metal zirconium powder is black, easily spontaneous combustion When issued a strong light; zirconium corrosion; mechanical properties, easy to process. Zirconium in the crust there is no single deposit, often with ilmenite, monazite and other co-exist, so difficult to extract. Nearly two decades, due to the development of science and technology, zirconium in the atomic energy industry and space rockets emerge, by
