Zirconium does not absorb neutrons, making it an ideal material for use in nuclear power stations. More than 90% of zirconium is used in this way. Nuclear reactors can have more than 100,000 metres of zirconium alloy tubing. With niobium, zirconium is superconductive at low temperatures and is used to make superconducting magnets.

Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon; zargun, "goldlike" or "as gold")), the most important source of zirconium. It is a lustrous, greywhite, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.

Zirconium. Zirconium is a very strong, malleable, ductile, lustrous silvergray metal. Its chemical and physical properties are similar to those of titanium. Zirconium is extremely resistant to heat and corrosion. Zirconium is lighter than steel and its hardness is similar to copper. When it is finely divided, the metal can spontaneously ignite ...

C) Two different samples of table salt are found to have the same ratio of sodium to chlorine. D) The atomic mass of bromine is found to be amu. E) Nitrogen dioxide always has a mass ratio of g O: 1 g N.
The extreme hardness and the abrasion characteristics exhibited by zirconium silicate (, a hardness number of on the Mohs scale for commercially available zirconium silicate, such as types used for grinding of glass) would suggest to one skilled in the art that zirconium silicate would seriously damage (, abrade and scratch) tooth ...
The principal economic source of zirconium is the zirconium silicate mineral, zircon (ZrSiO4). Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavymineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.

Zirconia is the crystal form of the transitional metal Zirconium and Zirconia implants are often marketed as "metal free". When the zirconium is treated, stabilized and converted into its crystal phase, it becomes a ceramic so Zirconium Oxide, otherwise referred to as "Zirconia" technically can be called, "metal free".
