Zirconium - a rare refractory metal white and silver, the 40th element of the periodic table.Zirconium metal managed to get out of zircon (mineral) only in the early 19th century.
zirconium as the other refractory metals, such as vanadium, tungsten, molybdenum and others, is characterized by high resistance to corrosion.Also, zirconium can not be exposed to the environment, it is resistant to solutions of organic acids and alkalis.
use zirconium
most widely used zirconium is in the steel industry.Zirconium has a deoxidizing effect and also decreases the amount of gas and sulfur, which are in the composition of the steel, thereby making it less ductile.
Steel, where used as an alloying element zirconium used for the production of armor plates.0.1% zirconium, which is included in the composition of the steel and increases its resistance to loads in two times.
By use of zirconium is not far behind and nonferrous metallurgy.Zirconium included in the aluminum alloys, improving its heat resistance.In the composition of magnesium alloys, zirconium improves their resistance to corrosion.
Refractoriness zirconium and its corrosion resistance cause widespread use of zirconium in various industries.Catalysts, laboratory and medical equipment, the die for manufacturing synthetic fibers, reinforcement parts hot - not a complete list of products manufactured from zirconium.
addition to industrial applications (nuclear power, pyrotechnics, etc.), Due to the curative and antiseptic properties, zirconium is used in medicine.
zirconium alloy showed excellent compatibility with biological tissues and a positive influence on them, in addition, they did not have an irritating effect on the bone and soft tissue.So, for example, zirconium earrings promote healing after piercing the earlobe for a few days before the gold earrings.According to medical research, the condition of patients who constantly wore zirconium products of a noticeably improved.
cases of dermatitis, eczema children, diseases of the musculoskeletal system and spine, as well as fractures of zirconia has a beneficial effect, a positive effect was observed in more than 90% of patients.
Zirconium is used as a material for dental implants and plates for maxillo-facial surgery.
for health purposes are not as popular jewelry made of zirconium.The anodic oxide film allows the zirconium to give any color and shade.Exquisite design, unusual color, lightness and extraordinary strength, resistance to aggressive environment is what sets zirconium products of the rest.
