0 (symbol Zr) a silver-grey/silver-gray metallic element that is found mainly in zircon, and is very resistant to corrosion. -- zirkonium
As a pure powder, zirconium hydrides are used as hydrogenation catalysts, in powder metallurgy, and as getters in the vacuum tube industry.
In this process, the strongly coordinating methyl group transfers to the boron to expose a reactive site on zirconium.
Titanium, scandium, and zirconium form stable chemical compounds called metal hydrides when combined with hydrogen or its isotopes.
Zirconium silicate is usually colorless, but impurities induce various colorations.
Typical materials that are welded include titanium, beryllium, and zirconium.
Many systems use an aluminium oxide or zirconium oxide or zirconia core instead of metal that makes complete porcelain restorations.
After zirconium was chosen as material for nuclear reactor programs in the 1940s, a separation method had to be developed.
It is an unusual ceramic, having relatively high thermal and electrical conductivities, properties it shares with isostructural titanium diboride and zirconium diboride.
