Application of zirconium materials in nuclear power plant.

Application of zirconium materials in nuclear power plant.

Zirconium powder is flammable in air and can be used as detonating detonator and smokeless powder.

Zirconium can be used as an additive for high quality steel deoxidization to sulfur, and is also a component of armor steel, artillery steel, stainless steel and heat resistant steel.

Zirconium is an important alloy element of magnesium alloy, which can improve the tensile strength and processing properties of magnesium alloy.Zirconium is also a modifier of aluminum magnesium alloy, which can refine grain.

Zirconia and zircon are the most valuable compounds in refractories.Zirconium dioxide is the main material of new ceramic and cannot be used as a heating material to resist high temperature oxidation.Zirconium dioxide can be used as an additive for acid resistant enamel and glass, which can significantly improve the elasticity, chemical stability and heat resistance of glass.Zircon has strong light reflection properties and good thermal stability. It can be used as a sunscreen in ceramics and glass.

Zirconium can absorb oxygen, hydrogen, ammonia and other gases in a large amount during heating. It is the ideal getter, such as the use of zirconium powder as the degassing agent in the tube, and the zirconium wire as the grid support, anode bracket and so on.

Powdered iron is mixed with zirconium nitrate for flash powder.Zirconium is used almost exclusively as a shell for uranium fuel elements in nuclear reactors.It is also used to make photoflash and corrosion-resistant containers and pipes, especially for hydrochloric acid and sulfuric acid.Zirconium chemicals can be used as crosslinking agents for polymers.

From the military's point of view, only one thousandth of the zirconium is added to the steel, and the hardness and strength will be amazingly high.Armoured steel, steel, stainless steel and heat-resistant steel containing zirconium are important materials for the manufacture of armored vehicles, tanks, artillery and bulletproof boards.

From the atomic and nuclear power, zirconium have prominent nuclear power, is indispensable to develop atomic energy industry materials, widely used zirconium large nuclear plant in our country, if use nuclear power generation, every one million kilowatts of power generation capacity, a year will consume between 20 and 25 tons of metal zirconium.A thirty thousand horsepower;Nuclear submarines use zirconium and zirconium alloys for nuclear fuel kits and pressure tubes, and zirconium is used for 20 to 30 tons.
Zirconium is a kind of rare metal, has the amazing corrosion resistance, high melting point, high hardness and strength features, is widely used in aerospace, military industry, nuclear, atomic energy fields."The god six" used on corrosion resistance, high resistance of titanium products, its corrosion resistance is much less than the zirconium, its melting point of 1600 degrees or so, and the melting point of zirconium is above 1800 degrees, zirconium dioxide the melting point of 2700 degrees, so the zirconium as aerospace material, its performance is greatly superior to the titanium
