Zirconium [TABLE=align: center] [TR] [TD][/TD] [/TR] [TR] [TD]Zirconium Ring[/TD] [/TR] [/TABLE] - Zirconium has a H.C.P. /B.C.C. structure. - Its melting point is 1852 °C. - It has a density of 6.55 gms/cm3. - It has a hardness of 140 V.H.N. - Zirconium is used for cladding fuel elements and for structural components in water-cooled systems. - Since zirconium has a relatively poor resistance to CO2 at high temperatures, 0.5% Cu, 0.5% Mo additions make it suitable for gas cooled reactors. This addition raises tensile strength and improves creep resistance at 450 °C.
