Zirconium is a rare metal, has an amazing corrosion resistance, high melting point, high hardness and strength characteristics, widely used in aerospace, military industry, nuclear reactions, atomic energy field. The "god six" on the use of corrosion resistance, high temperature resistant titanium products, the corrosion resistance is much less than the zirconium, its melting point around 1600 degrees, and the melting point of zirconium is in 1800 degrees above, zirconium dioxide melting point is as high as 2700 degrees above, so zirconium as aerospace materials, its all aspects of superior performance greatly in titanium.
Zirconium USES:
From military perspective, in one over one thousand of the steel as long as added zirconium, hardness and strength will be wonderfully catch high. Containing zirconium armor steel, artillery forging steel, stainless steel and heat resistant steel etc is manufacturing armored vehicles, tanks, artillery and weapons such as bulletproof panels of the important material.
From the atomic energy and nuclear power perspective, zirconium have prominent nuclear sex, is developing nuclear energy industry indispensable materials, China's large nuclear power plants are generally use zirconium, if use nuclear power generation, every one million kilowatts of power generation capacity, one year is about to consume 20 to 25 tons of metal zirconium. A ship thirty thousand horsepower; Nuclear submarine with zirconium and zirconium alloys for nuclear fuel bag set and pressure pipe, zirconium the usage of the 20 to 30 tons
The output of zirconium:
Zirconium products main raw material is zirconium English sand, 90% of the world's oxygen chlorinated zirconium (primary products) production capacity in China. At present, the domestic zirconium processing capacity of 120000 tons/year, the actual production in the 80000 tons/year, more than 85% export, at present the global zirconium market demand, the price of zirconium now about $12000 per ton, and prices are still rising.
The representation of the metal zirconium steel, under normal temperature, the surface is dense oxide layer cover, but still have the metallic luster. Powder zirconium for dark grey. Metal melting point for 1852 ℃ zirconium, density of 6.49 g / 3 cm. The plasticity is good, easy to processing into boards, silk, etc. In the heat of zirconium can absorb oxygen, hydrogen, nitrogen, gas, can be used for hydrogen storage material. The corrosion resistance of zirconium than titanium well, close to nb and ta. Zirconium and Ha is chemical properties history, and symbiosis with similar in the two metal, and containing radioactive substances. In the crust of the 20 th zirconium content, almost equal with chrome. At present, the nature of industrial value has containing zirconium mineral, basically have zirconium stones and inclined zircon.
