Zirconium is used in jewelry, in the nuclear industry for cladding fuel elements since it has a low absorption cross section for neutrons, in chemical industry where corrosive agents are employed, is used as an alloying agent in steel and for making surgical appliances, it also superconducts at low temperatures and zirconium/niobium alloys are used to make superconductor magnets, and is used as a "getter" in vacuum tubes, in flash bulbs for Photography, in explosive primers, and in lamp filaments.
Sorry that's all I could come up with for right now, I have to get back to my research but i hope it answers your question.

Some applications of the alloy zirconium-aluminium alloy: bearing assembly, ballast, casting, step soldering, and radiation shielding, components for planes.
Zirconium is commonly used in nuclear reactors for its resistance to corrosion. It is also used in ceramics, refractory materials, and as an opacifier in glazes and enamels. In addition, zirconium compounds are used in catalysts, propellants, and in the production of high-performance alloys.
Zirconium is a natural chemical element; zirconium is found in some minerals.
Zirconium is a natural element found in some minerals.
Additive in tooth pastes (as abrasive), component of some anti perspirants, oxygen sensors, zirconium dioxide knifes, golf clubs with zirconium dioxide or zirconium, electronic devices in a case of zirconium dioxide, component in some cell phones (zirconium titanate), etc.
The alloy zirconium-aluminium is used for some components for planes.
Zirconium does have radioactive isotopes, but the main ones used in industry are not radioactive.
Zirconium is used in nuclear energy applications such as fuel cladding. Other uses are in alloys, fireworks, and flashbulbs and as a scavenger for oxygen and other gases.
Zirconium is considered as a not dangerous metal; but the inhalation of zirconium fine powders must be avoided (a cause of pulmonary diseases).
Zirconium can combine with elements such as oxygen, nitrogen, hydrogen, and carbon to form various compounds. These combinations lead to the formation of zirconium oxide, zirconium nitride, zirconium hydride, and zirconium carbide.
The toxicity of zirconium is not very important; only the inhalation of zirconium and zirconium compounds powders is dangerous (as for many other materials) - leading to pneumoconioses. Also zirconium can be pyrophoric at high temperatures, in powdr form. Zirconium is used for surgical implants, stomatology - as zirconium dioxide, im some cosmetics. No nutitional use.
