釩是近代重要的金屬之一。有的文献記載它是在1803年由Del Rio所发現,有的記載是在1801年由墨西哥人所发現,不管其在何时发現,而对釩的提取是在本世紀才开始的。枴据最近的数据,釩的一些物理常数如下: 化学符号 V 原子量 50.95 原子序数 23 原子体积 9.1 同位素 50、51 比重(克—公分~3) 6.07 熔点 1700±20℃沸点 3000～3400℃比电阻(在O℃) 19×10~(-6)欧姆—公分 結晶格子体心立方晶格布氏硬度 260 磁性具有顺磁性 緻密的金屬釩呈銀白色,常溫于空气中很稳定,加热在300℃以下时,并不发生氧化。粉末狀态的釩,当加热至高溫时,很容易在空气中燃燒。
Vanadium is one of the most important metals in modern times. It has been documented in literature that it was discovered by Del Rio in 1803 and some recorded by Mexicans in 1801, no matter when it was discovered, and the extraction of vanadium was not until this century . According to recent data, some physical constants for vanadium are as follows: Chemical symbol V Atomic weight 50.95 Atomic number 23 Atomic volume 9.1 Isotopes 50, 51 Specific Gravity (g - cm3) 6.07 Melting point 1700 ± 20 ℃ Boiling point 3000 ~ 3400 ℃ Specific resistance At O ℃) 19 × 10 ~ (-6) ohm-cm lattice lattice cubical lattice Brinell hardness of 260 magnetic with paramagnetic dense metal vanadium was silver white, very stable at room temperature in the air, heated below 300 ℃ No oxidation occurs. Vanadium powder, when heated to high temperatures, it is easy to burn in the air.
