Zirconium is an important alloying element of magnesium alloy, which can improve the tensile strength and workability of magnesium alloy. Zirconium is also an aluminum-magnesium alloy modifier, which can refine grains.

Zirconium dioxide is the main material of the new ceramic and can not be used as the heating material to resist high temperature oxidation. 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 can absorb a large amount of oxygen, ammonia and other gases when heating, is an ideal getter, such as the electron tube with zirconium powder as a degassing agent, with zirconium wire zirconium plate as grid support, anode support, etc.

Powdered iron mixed with zirconium nitrate can be used as glitter. Zirconium is used almost exclusively as a cladding for uranium fuel elements in nuclear reactors. It is also used to make flash lamps for photography, and corrosion resistant vessels and pipes, especially hydrochloric and sulphuric 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 zirconium, hardness and strength will be surprisingly high. Zirconium-containing armor steel, cannon forging steel, stainless steel and heat-resistant steel are important materials for the manufacture of armored vehicles, tanks, artillery and bulletproof plates.

From the perspective of atomic energy and nuclear energy, zirconium has outstanding nuclear energy and is an indispensable material for the development of atomic energy industry. If nuclear power is used to generate electricity, 20 to 25 tons of zirconium metal will be consumed per one million kilowatts of power generation capacity a year. A ship with 30,000 horsepower; Nuclear submarines use zirconium and zirconium alloys as nuclear fuel jackets and pressure tubes. The amount of zirconium used is 20 to 30 tons.

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.
