Zirconium

The resulting metal is sintered until sufficiently ductile for metalworking.[7] Separation of zirconium and hafnium[edit] Commercial zirconium metal typically contains 1–3% of hafnium,[18] which is usually not problematic because the chemical properties of hafnium and zirconium are very similar.

Oxide Ceramics – Zirconium Oxide (ZrO2)

The oxide ceramic zirconium oxide, or zirconia (ZrO2) is a ceramic material with very high crack propagation resistance and thermal expansion. These properties are the reason why zirconium oxide ceramics from CeramTec are chosen to join ceramic and steel.

ZIRCONIUM CAS#: 7440-67-7 - ChemicalBook

The inherent toxicity of zirconium compounds is low. Hafnium is invariably found in zirconium ores, and the separation is difficult. Commercial-grade zirconium contains from 1 to 3% hafnium. Zirconium has a low absorption cross section for neutrons, and is therefore used for nuclear energy applications, such as for cladding fuel elements.

Zirconium — Wikipedia Republished // WIKI 2

Zirconium is a chemical element with symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon, the most important source of zirconium.The word zircon comes from the Persian word zargun زرگون, meaning "gold-colored". It is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium.

Hafnium - Wikipedia

Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals.Its existence was predicted by Dmitri Mendeleev in 1869, though it was not identified until 1923, by Coster and Hevesy, making it the last stable element to be discovered.
