What are 3 uses of zirconium?
Zirconium(IV) oxide is used in ultra-strong ceramics. It is used to make crucibles that will withstand heat-shock, furnace linings, foundry bricks, abrasives and by the glass and ceramics industries. It is so strong that even scissors and knives can be made from it.
Is zirconium poisonous?
Toxicity Most zirconium compounds have low systemic toxicity due to their poor solubility. However, some soluble compounds, such as zirconium tetrachloride, are irritants and may cause corrosive injury. In addition, skin and lung granulomas have been reported following repeated zirconium exposure.
What is zirconium most commonly used for?
nuclear reactors
Zirconium is a corrosion resistant metal that is used in high performance pumps and valves. Since it also does not easily absorb neutrons, zirconium is widely used in nuclear reactors. The nuclear power industry uses nearly 90% of the zirconium produced each year, which must be nearly free of hafnium.
What color is zirconium?
silver-gray
Zirconium is a silver-gray transition metal, a type of element that is malleable and ductile and easily forms stable compounds. It is also highly resistant to corrosion. Zirconium and its alloys have been used for centuries in a wide variety of ways.
What reacts with zirconium?
Zirconium does react with the halogens upon warming to form zirconium(IV) halides. So, zirconium reacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2, to form respectively zirconium(IV) bromide, ZrF4, zirconium(IV) chloride, ZrCl4, zirconium(IV) bromide, ZrBr4, and zirconium(IV) iodide, ZrI4.
What does zirconium smell like?
Appearance and Odor: White, heavy powder or crystal, no odor.
How strong is zirconium?
Being made of crystal, zirconium is nearly indestructible, easily withstanding the most vigorous chewing and biting activities. In fact, zirconium is five times as strong as porcelain! Zirconium crowns are milled in a way that they are nearly indestructible.
Where was zirconium found?
Martin Heinrich Klaproth, a German chemist, discovered zirconium in 1789 in a sample of zircon from Sri Lanka, according to Chemicool.
How is zirconium made?
Fused zirconia (zirconium oxide) is produced through the reduction and fusion of zircon sand (zirconium silicate). Zircon is mixed with coke and heated to its fusion point (in excess of 2,800 ̊C) in an electric arc furnace where it dissociates to zirconium oxide and fumed silica.

Why is zirconium black?
In its natural state, zirconium is a silver-grey color. It earns its stark black appearance through our proprietary heating process, in which a layer of hard black oxide grows on the metal. This black layer is much harder than raw zirconium, but it is very thin.
