Model Number: GK-329 Brand Name: GENPHOAL Key Specifications/Special Features: Specifications:Zirconium is a chemical element with symbol Zr and atomic number 40Name of zirconium is taken from the name of the mineral zircon, the most important source of zirconiumWord zircon comes from the Persian word argon meaning gold-colored[4] Lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent and titaniumZirconium is mainly used as a refractory and pacifier, although it is used in small amounts as an alloying agent for its strong resistance to corrosionZirconium forms a variety of inorganic and oregano metallic compounds such as zirconium dioxide and zirconocene dichloride, respectivelyFive isotopes occur naturally, three of which are stableZirconium compounds have no known biological role





Characteristics:
Zirconium is a lustrous, grayish-white, soft, ductile and malleable metal which is solid at room temperature, though it becomes hard and brittle at lower purities
In powder form, zirconium is highly flammable, but the solid form is far less prone to ignition
Zirconium is highly resistant to corrosion by alkalis, acids, salt water and other agents
However, it will dissolve in hydrochloric and sulfuric acid, especially when fluorine is present
Alloys with zinc become magnetic below 35K



Zirconium's melting point is 1855°C (3371°F) and its boiling point is 4371°C (7900°F)
Zirconium has an electro negativity of 1.33 on the Pauling scale
Of the elements within d-block, zirconium has the fourth lowest electro negativity after yttrium, lutetium and hafnium



At room temperature zirconium exhibits a hexagonally close packed crystal structure, α-Zr, which changes to β-Zr a body-centered cubic crystal structure at 863 °C Zirconium exists in the β-phase until the melting point
