锆系元素周期律中的第四十号元素。由于金属锆在抗腐蚀性、机械强度、延展性及中子吸收截面等方面具有优良的性能,而被广泛应用于原子能工业。我国从五十年代开始对锆进行研究和试验性生产,到六十年代开始研究生产原子能级海绵锆。近年来随着我国原子能工业(例原子能反应堆研究、原子能发电、原子能核潜艇……)宇宙航空以及无线电、化工等工业迅猛发展,因而对锆的需要量成倍增长。
Element Zirconium Periodicity of the fortieth element. Due to its excellent properties in corrosion resistance, mechanical strength, ductility and neutron absorption cross-section, zirconium metal is widely used in atomic energy industry. Since the 1950s, China began researching and experimentally producing zirconium. By the 1960s, it began to study the production of atomic-grade sponge zirconium. In recent years, with the rapid development of China’s atomic energy industry (such as atomic energy reactor research, nuclear power generation, atomic nuclear submarines ... ...) and aerospace, radio and chemical industries, the demand for zirconium has doubled.
