Uses of zirconium metal Uses of zirconium

Zirconium has a small thermal neutron capture cross section and outstanding nuclear performance. It is an indispensable material for the development of atomic energy industry and can be used as a structural material for reactor core. Zirconium powder burns easily in air and can be used as detonator and smokeless powder. Zirconium metal can be used in high quality steel deoxidation and sulfur additives, is also armor steel, cannon steel, stainless steel and heat-resistant steel components. Zirconium is an important alloying element of magnesium alloy, which can improve the tensile strength and machining property of magnesium alloy. Zirconium or aluminum magnesium alloy metamorphic agent, can refine the grain. Zirconium dioxide and zircon are the most valuable compounds in refractories. Dioxide fault is the main material of new pottery www.ti-metals.com porcelain, can not be used as high temperature oxidation resistance heating material. Zirconium dioxide can be used as an additive for acid-resistant enamel and glass. It can significantly improve the elasticity, chemical stability and heat resistance of glass. Zircon has strong light reflection and good thermal stability. It can be used as a sunblock in ceramics and glass. Zirconium metal can absorb oxygen, hydrogen, ammonia and other gases in large quantities when heating, is an ideal getter, such as electron tube with zirconium powder as a degassing agent, zirconium metal wire zirconium plate as grid support, anode support, etc.

Powdered iron mixed with nitric acid can be used as glitter. Zirconium is used almost exclusively as a cladding for uranium fuel components in nuclear reactors. It is also used in the manufacture of flash lamps for photography, and corrosion resistant vessels and pipes, especially hydrochloric acid and sulfuric acid. Zirconium chemicals can be used as crosslinking agents for polymers.

From the military point of view, steel as long as add one thousand of the wrong, hardness and strength will be surprisingly high. Faulty armor steel, cannon forging steel, stainless steel and heat-resistant steel are important materials in the manufacture of armored vehicles, tanks, artillery and bulletproof plates.

From the perspective of atomic energy and nuclear energy, metal has outstanding nuclear energy, is an indispensable material for the development of atomic energy industry, China's large nuclear power plants generally use the wrong material, if nuclear power generation, every one million kilowatts of power generation capacity, 20 to 25 tons of zirconium metal a year will be consumed. A ship with 30,000 horsepower; Nuclear submarines use zirconium and zirconium alloys as nuclear fuel jackets and pressure tubes, and 20 to 30 tons of metal zirconium is used. Zirconium is a kind of rare metal, with amazing corrosion resistance, extremely high melting point, ultra-high hardness and strength characteristics, is widely used in aerospace, military, nuclear reaction, atomic energy fields. The "God six" on the use of corrosion resistance, high resistance of titanium products, its corrosion resistance is far less than zirconium, its melting point about 1600 degrees, and the melting point of the metal is above 1800 degrees, the melting point of the wrong is as high as 2700 degrees above, so the wrong as aerospace materials, its performance in all aspects is greatly superior to titanium.

The ideal getter when we get to know lithium and titanium, we know that it loves to make friends with gas. Metals also have this temper. They strongly absorb nitrogen, hydrogen, oxygen and other gases. At temperatures above 90 degrees Celsius, for example, zirconium absorbs nitrogen vigorously; At 200 degrees Celsius, 100 grams of zirconium metal can absorb 817 liters of hydrogen, more than 800,000 times as much as iron.

This quirk of zirconium has caused great problems for the workers who smelt it, but it has benefited in other ways.

For example, in the electric vacuum industry, zirconium powder is widely applied on the surface of the anode and other heated parts of the electric vacuum element and instrument to absorb the residual gas in the vacuum tube and make the vacuum tube and other electric vacuum instrument with high vacuum, so as to improve their quality and prolong their service time.

Zirconium can also be used as a "vitamin" in the metallurgical industry, exerting its powerful deoxidation, ammonia, sulfur removal. The hardness and strength of steel will increase dramatically if only one thousandth error is added to it; Steel, stainless steel and heat-resistant steel are important materials for the manufacture of armored vehicles, tanks, cannons, bulletproof plates and other defense weapons. Adding zirconium into copper, pumping salty copper wire, conductive ability does not weaken, but the melting point is greatly improved, used as high voltage wire very suitable. Zinc-magnesium alloys containing zirconium, which are light and high temperature resistant, are twice as strong as ordinary magnesium alloys and can be used in the manufacture of jet engine components.

We have mentioned metallic zirconium powder before. Zirconium powder is characterized by its low ignition point and rapid combustion rate, and can be used as primer for detonators, advanced detonators that can explode even under water. Zirconium metal powder plus oxidizer. It's like adding fuel to a fire, burning it up in blinding light, good material for tracer bullets and flares.
