- 锆的应用领域非常广泛，主要以硅酸锆、氧化锆的形式应用于陶瓷、耐火材料等领域。仅有3%-4%的锆矿石被加工成
金属锆(或称海绵锆)，再进一步加工成各种锆材。由于金属锆具有热中子吸收截面小的特性，使得金属锆拥有优异的核性能，核级锆就是应用这个特性将其用作核动力航空母舰、核潜艇和民用发电反应堆的结构材料、铀燃料元件的包壳等。核级锆可算是国家重要的战略金属，与核工业的发展密切关联。
- 锆作为一种活性金属，在室温中就会形成氧化膜，这层氧化膜使得锆及其合金具有优良的抗腐蚀性能。同时锆又具有良好的力学和传热性能，再加上显著的成本优势，使它成为当今石油化工领域优异的耐蚀结构材料。
- 在化工耐酸碱的设备、军工、电子行业中应用的锆叫做工业级锆。从加工难易程度、工艺水平和科技含量等方面来看，金属锆及其合金制品处于产业链顶端。
Zirconium has a widerange of applications, mainly in the form of zirconium silicate and zirconia,which are used in ceramics, refractory materials and other fields. Only 3%-4% ofzirconium ore is processed into zirconium metal (or sponge zirconium), which isfurther processed into various zirconium materials. Due to the small thermal neutronabsorption cross-section, zirconium metal has excellent nuclear properties, andnuclear-grade zirconium is used as a structural material for nuclear-powered aircraftcarriers, nuclear submarines and civil power generation reactors, and as a claddingfor uranium fuel elements. Nuclear-grade zirconium can be regarded as an importantstrategic metal in the country, which is closely related to the development of thenuclear industry. As an active metal, zirconium will form an oxide film at roomtemperature, which makes zirconium and its alloys have excellent corrosion resistance.At the same time, zirconium has good mechanical and heat transfer properties, coupledwith significant cost advantages, making it an excellent corrosion-resistant structuralmaterial in the petrochemical industry today. The zirconium used in chemical acidand alkali resistant equipment, military industry, and electronics industries iscalled industrial-grade zirconium. From the perspective of processing difficulty,process level and scientific and technological content, zirconium metal and itsalloy products are at the top of the industrial chain.
