Zirconium | chemical element | Britannica
Zirconium is relatively abundant in Earth’s crust, but not in concentrated deposits, and is characteristically observed in S-type stars.The mineral zircon, which is generally found in alluvial deposits in stream beds, ocean beaches, or old lake beds, is the only commercial source of zirconium.

The palladium–zirconium phase diagram - ScienceDirect
The palladium–zirconium phase diagram has been re-investigated over its entire composition range. The revised diagram includes two intermediate phases, Pd 4 Zr 3 and Pd 11 Zr 9, which did not appear in previous studies.The crystal structures of the new phases resemble the B2-type structure although the atoms are displaced significantly from the cubic lattice sites.
