what is Zirconium
Zirconium is a rare metal, with amazing corrosion resistance, extremely high melting point, ultra-high hardness and strength and other characteristics, is widely used in aerospace, military, nuclear reaction, atomic energy fields.
Zirconium powder is flammable in air and can be used as detonator and smokeless powder. Zirconium can be used as an additive to deoxidize and desulphurize high quality steels. It is also a component of armor steels, cannon steels, stainless steels and heat resistant steels.
Zirconium is an important alloying element in magnesium alloys, which can improve the tensile strength and processing properties of magnesium alloys. Zirconium is also a modifier of aluminum-magnesium alloy, which can refine the grain.
Zirconium can absorb oxygen, hydrogen, ammonia and other gases in large quantities when heated, and it is an ideal getter.
Powdered iron mixed with zirconium nitrate as a flash powder. Zirconium is used almost entirely as the cladding for uranium fuel elements in nuclear reactors. It is also used to make photoflash lamps, as well as corrosion-resistant containers and tubes, especially those resistant to hydrochloric and sulfuric acid. Zirconium chemicals can be used as crosslinking agents for polymers.
From a military point of view, steel as long as the addition of 1, 000 zirconium, hardness and strength will be surprisingly high. Armor steel containing zirconium, artillery forgings steel, stainless steel and heat resistant steel are important materials for making armored vehicles, tanks, artillery and bulletproof plate.
From the point of view of atomic energy and nuclear energy, zirconium has outstanding nuclear energy, is an indispensable material for the development of atomic energy industry, China's large nuclear power plants are generally used zirconium, if the use of nuclear power generation, every million kilowatts of power generation capacity, a year will consume 20 to 25 tons of zirconium. A 30,000-horsepower ship; Nuclear submarines use zirconium and zirconium alloy as the nuclear fuel jacket and pressure tube, the use of zirconium up to 20 to 30 tons.
