Zirconium crowns have quickly become the preferred material for dental crowns. Zirconium is a very strong substance that can endure wear and tear of everyday use. When looking at Zirconium crowns from an aesthetic point it is clear and very similar to a natural .
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 is used for the fabrication of fuel cladding tubes for existing nuclear reactors (PWR, pressurized water reactor). The two major ore minerals (zircon and zirconium silicate) treated of the production of zirconium metal contain from to several percent hafnium, which substitutes for zirconium in the mineral lattice [8].
Zirconium Carbide can also be fabricated by solution based processing. This is achieved by refluxing a metal oxide with acetylacetone. Another method of fabrication is chemical vapour deposition. This is achieved by heating a zirconium sponge and parsing halide gas through it.

2. Synthesis Methods. Zirconium and hafnium carbides and nitrides can be synthesized by direct reaction of metal or metal hydride powders with graphite or N reactions are strongly exothermic and can be used in a selfpropagated high temperature synthesis (SHS) process [].The reaction of oxides with graphite (carbothermal process) is widely used for industrial synthesis of bulk carbide ...
Zirconium crowns can withstand the biting pressure of the front teeth as well as back teeth grinding. The look of zirconium crowns and bridges is so close to natural teeth that it is hard to tell the difference and it is this quality which makes it very useable within dental work. Zirconium crowns can be fixed using traditional dental cements.
