Zirconium Production Technology Parameters
Zirconium production technology parameters are as followings:
Zirconium and titanium have many similar physical and chemical properties. For example, zirconium and titanium all have high melting points. The chemical activity of zirconium and titanium are very high. Zirconium has higher chemical activity than that of titanium. While, titanium and zirconium all have high corrosion resistance.
In the majority of strong corrosive medium, zirconium has better corrosion resistan than that of titanium, that is why many chemical equipments are made of zirconium with the fact that zirconium is more expensive than titanium. Zirconium also belongs to passivated metal. So zirconium is very easy to combine with oxygen and form dense passivated filmon the surface of zirconium. Zirconium is able to resist corrosion of most organic acid, inorganic acid, alkali, fuse salt, high temperature water and liquid metal. Zirconium has excellent corrosion resistance under the normal boiling point in all concentrations of hydrochloric acid.
But zirconium has the possibility of hydrogenation at above 149 ℃ in hydrochloric acid. Under 250 ℃, zirconium can be used in not more than 70% nitric acid, but zirconium is easy to detonate in concentrated nitric acid. In organic acid, zirconium has corrosion resistance. While, zirconium is not resistant to hydrofluoric acid, sulfuric acid, phosphoric acid, aqua regia, bromide, hydrobromic acid, fluorosilicic acid, calcium hypochlorite, fluoboric acid. In the oxidation of chloride, such as copper chloride, ferric chloride solution, zirconium is not able to resist corrosion. Zirconium can resist corrosion of reducing chloride solution.
in the air, zirconium will seriously peel at 425 ℃, generate white zirconium oxide at 540 ℃, absorb oxygen and become embrittlement at 700 ℃ . Zirconium react with nitrogen at above 400 ℃.
