Introduction And Application Of Zirconium Powder

2018-10-10      View:

Zirconium is a chemical element whose chemical symbol is Zr, which has an atomic number of 40 and is a high melting point metal that is light gray. Zirconium readily absorbs hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen, and its solubility in zirconium at 1000 °C can significantly increase its volume.


The surface of zirconium is easy to form an oxide film with a luster, so the appearance is similar to steel. It is corrosion resistant but soluble in hydrofluoric acid and aqua regia. At high temperatures, it reacts with non-metallic elements and many metal elements to form a solid solution.


Zirconium has good plasticity and is easy to process into sheets and wires. Zirconium can absorb a large amount of gases such as oxygen, hydrogen, and nitrogen when heated, and can be used as a hydrogen storage material. Zirconium has better corrosion resistance than titanium and is close to tantalum and niobium. Zirconium and strontium are two metals that are chemically similar and symbiotic together and contain radioactive materials.


Zirconium is a rare metal with amazing corrosion resistance, high melting point, high hardness and strength. It is widely used in aerospace, military, nuclear reaction and atomic energy fields. The melting point of zirconium is above 1800 degrees, and the melting point of zirconium dioxide is more than 2700 degrees. Therefore, zirconium is an aerospace material, and its performance in various aspects is much superior to that of titanium.
