Overview

Zirconium is a transition metal and has two structures, namely the alpha form of the hexagonal system and the beta form of the cubic system. Zirconium has a silver gray metallic luster in appearance. It is insoluble in water, slightly soluble in acid, soluble in hydrofluoric acid and aqua regia, etc. Its atomic weight is 91.224 and its density is 6.506 g/cm³.

Characteristics

Zirconium is highly plastic and resistant to high temperature, corrosion, radiation and acid. Zirconium can also store hydrogen and has good inspiratory properties at high temperatures. Zirconium reacts with water, acids and bases to release hydrogen; It can react with oxygen, hydrogen, nitrogen, halogen and other non-metallic elements to form zirconium containing binary compounds. Can absorb carbon monoxide and carbon dioxide under high temperature conditions, but also can react with zirconium tetrabromide and other substances.

Application

Pure zirconium metal has excellent acid and alkaline resistance, so it is used in the manufacture of reactors, pumps, heat exchangers, valves, agitators, nozzles, thermocouple bushing, conduit and container lining in chemical, pesticide, fertilizer and dye equipment. Zirconium wire can be used as the electrode head of air plasma cutting machine. Zirconium chips can be used as steel additives for deoxidation and nitrogen removal; It can also be used as grain refiner for the production of aluminum alloy. Zirconium powder can be used in powder metallurgy, the production of pyroluminant, and zirconium powder friction can emit high temperature enough to ignite hydrocarbon vapor bouquet, so it can be used in the military for the manufacture of bullets and shells fuse and high explosives, armor-piercing incendiaries and incensed cluster bombs and other weapons.
Zirconium can be alloyed with other metals or non-metals and has a wide range of applications in the atomic energy industry, electronics industry, medical device manufacturing and building materials manufacturing.
