Zirconium is also widely used in the vacuum industry. It can be used to make beautiful golden yellow. The industry has zirconium and titanium. It is also made of zirconium or titanium. Some people think that zirconium is closer to real gold. Hue, today I will talk about zirconium.
Zirconium readily absorbs hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen, and its solubility in zirconium at 1000 °C can significantly increase its volume. The surface of zirconium is easy to form an oxide film with a luster, so the appearance is similar to steel. It is corrosion resistant but soluble in hydrofluoric acid and aqua regia. At high temperatures, it reacts with non-metallic elements and many metal elements to form a solid solution. Zirconium has good plasticity and is easy to process into sheets and wires. Zirconium can absorb a large amount of gases such as oxygen, hydrogen, and nitrogen when heated, and can be used as a hydrogen storage material. Zirconium has better corrosion resistance than titanium and is close to tantalum and niobium. Zirconium and strontium are two metals that are chemically similar and symbiotic together and contain radioactive materials.
Zirconium, like lithium and titanium, strongly absorbs gases such as nitrogen, hydrogen, and oxygen. When the temperature exceeds nine hundred degrees Celsius, zirconium can absorb nitrogen violently; under the condition of two degrees Celsius, one hundred grams of metal zirconium can absorb 871 liters of hydrogen, equivalent to more than 800,000 times of iron. This characteristic of zirconium has been widely used. For example, in the electric vacuum industry, zirconium powder is widely used on the surface of the anode and other heated parts of electric vacuum components and meters to absorb residual gas in the vacuum tube to make a high vacuum. Tubes and other electric vacuum gauges improve their quality and extend their life.
Zirconium can also be used as a "vitamin" in the metallurgical industry to exert its powerful functions of deoxidation, nitrogen removal and desulfurization. As long as one thousandth of zirconium is added to the steel, the hardness and strength will increase dramatically. Zirconium-containing armor steel, stainless steel and heat-resistant steel are important materials for the manufacture of armored vehicles, tanks, cannons and bulletproof panels. . Zirconium is incorporated into copper and drawn into a copper wire. The electrical conductivity is not weakened, but the melting point is greatly improved. It is very suitable for use as a high voltage wire. Zirconium-containing zinc-magnesium alloy, which is light and high temperature resistant, is twice as strong as ordinary magnesium alloy and can be used in the manufacture of jet engine components.
Zirconium powder is characterized by low ignition point and fast burning speed, and can be used as a primer for detonating detonators. This advanced detonator can also explode even under water. Zirconium powder plus oxidant. This is like a fuel on the fire, burning and dazzling, is a good material for the manufacture of tracer and flare.
