Chemistry.
- : a metallic element found combined in zircon, baddeleyite, etc., resembling titanium chemically: used in steel metallurgy, as a scavenger, as a refractory, and as an opacifier in vitreous enamels. Symbol: Zr; atomic weight: 91.22; atomic number: 40; specific gravity: 6.49 at 20°C.
Examples
He specialized in research and development in zirconium products, and allegedly had distant ties to Iran.
The other source of vector is the reaction between the zirconium and water.
The zirconium alloy will react with water to produce hydrogen and oxide, but it also produces heat that has to be removed.
On the prolonged boiling of the filtrate, the oxide of titanium (and oxide of zirconium, if any) is precipitated.
Zirconium is exactly like titanium in form, but contains a large number of atoms.
On the one side is carbon, with below it titanium and zirconium; on the other silicon, with germanium and tin.
Zirconium chlorid has an astringent taste, and if fed repeatedly will cause the metallic astringent action.
A lamp-filament of titanium and zirconium with electric lamps or with alloys?
