Vanadium has a number of excellent physical properties and chemical
properties, so the use of vanadium is very extensive, there is metal
"vitamins" known. The initial vanadium is mostly used in steel, which
improves the grain coarsening temperature by refining the microstructure
and grain of the steel, thus increasing the strength, toughness and
wear resistance of the steel. Later, the excellent improvement of
vanadium in TI alloy was gradually discovered, and applied to the
aerospace field, which made the aerospace industry make a breakthrough
progress. With the rapid development of science and technology, the
demand for new materials is increasing. Vanadium is more and more widely
used in the field of non steel, including aerospace, chemistry,
batteries, pigments, glass, optics, medicine and many other fields. Total

auxiliary materials: the properties of vanadium are similar to those of
Tantalum and niobium, and after it was discovered, the British chemist
Roscoe studied its properties, confirming that it was similar to
tantalum and niobium, which established the foundation for three of them
to build a division in the periodic table of elements of the CPC. Can
be distinguished metal-vanadium vanadium traces all over the world.
