I have compiled a list of sources for the elements that are available to the amateur chemist. Zirconium will be discussed here. 


Zirconium, a silvery gray left side transition metal, is similar to titanium. It is quite unreactive in bulk form but burns vigorously in powdered form, forming zirconium dioxide, which is better known as cubic zirconia when in a crystalline form. Zirconium forms tetravalent covalently-bonded compounds that have low melting points, just like titanium. Zirconium is transparent to neutrons and heat-resistant, making it useful for fuel rod claddings in nuclear reactors. Zirconium is quite corrosion resistant but will dissolve slowly in hydrochloric acid, just like titanium.


In element form: Some body jewelry is made of zirconium metal. Some vacuum tubes use zirconium alloy getters. Old flash bulbs for cameras sometimes used zirconium wool.


In compound form: Lead titanate zirconate is used as a piezoelectric element. Both zircon (zirconium silicate) and cubic zirconia (zirconium dioxide) are used in jewelry. Zirconium dioxide is also used as an abrasive.


Here is my sample of zirconium. It is a lead titanate zirconate (supposedly) piezoelectric element from an igniter.

How did you remove it without breaking it ?

Is it found in any spark igniter ?
