Zirconium is a lustrous steel-gray metal with a yellowish tinge, In conditions of high and cryogenic temperatures, it retains its characteristics. It is paramagnetic, heat-resistant and corrosion-resistant material, ductile m plastic. Get it from the ore concentrate, as well as remelting of zirconium waste. Extraordinary properties of zirconium are used for alloying of critical alloys and steels, to which this metal lends not only heat and corrosion resistant, but also increases manufacturability.
More than a hundred years, from the time of allocation Clarocom pure Zirconia, it remained a rare exotic metal, also fairly expensive for industrial applications, Used mainly in laboratory practice and jewelers to create exclusive jewelry. But in the last century during the lifetime of just one generation it has become an indispensable construction material. Industrial use of zirconium started with the 1930-ies.
The proportion of α-zirconium 6.5 g/cm3; specific heat (at 25−100°C) 0,291 kJ/(kg•K), t° melting point 1855 °C; t° boiling point 4409 °C; coefficient of thermal conductivity (50°C) 20, and 96 W/(m•K); temperature linear expansion coefficient (20−400°C) to 6.9x10-6; specific electrical resistivity (20 °C) 0.44 Omhm2/m. the Zirconia becomes a superconductor at a temperature of 0.7°K. This paramagnetic metal, specific magnetic susceptibility increases with heat and at t°-73°C reaches to 1.28x10-6 and 1.41x10-6 at t° 327 °C. the capture cross Section for thermal neutrons is 0.18x10-28 m2 and with a mixture of hafnium increases. Pure Zirconia can be easily hot and cold working (forging, rolling, stamping). The admixture of nitrogen, oxygen, hydrogen, sulfur and carbon makes Zirconia fragile. The modulus of elasticity (20 °C) 9700 kgf/mm2; the limit of the tensile strength is 25.3 kgf/mm2; Brinell hardness number 64−67 kgf/mm2; hardness is strongly dependent on the admixture of oxygen. Zirconium is not susceptible to cold pressure treatment at 0.2% O2 or more. The only plant for the production of zirconium in Russia — Chepetsky mechanical plant (Glazov, Udmurtia). This metal has been used since the 1930-ies, but because of the high cost — very limited.
The percentage grades of Zirconia
Since the Zirconia delays the radiation has a narrow capture cross section for thermal neutrons and resistance to aggressive environments — it is used in nuclear power. Zirconium tubes are used primarily in heat and as a shell for the reactor core. Due to its physical and chemical properties, such a tube provides a safe work TVEL. It should be remembered that up to 300 °C this metal does not react with superheated steam, above. 700 °C can begin paraseraya exothermic reaction, which can lead to accident in nuclear reactors with water coolant.
