2. Zirconium alloys - Wikipedia

   en.wikipedia.org/wiki/Zirconium_alloys

   Corrosion resistance of zirconium alloys is enhanced by intentional development of thicker passivation layer of black lustrous zirconium oxide. Nitride coatings might also be used. Whereas there is no consensus on whether zirconium and zirconium alloy have the same oxidation rate, Zircaloys 2 and 4 do behave very similarly in this respect.

3. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   Another technique first applied to quartz and topaz has also been adapted to cubic zirconia: An iridescent effect created by vacuum-sputtering onto finished stones an extremely thin layer of a precious metal (typically gold), or certain metal oxides, metal nitrides, or other coatings. [14] This material is marketed as "mystic" by many dealers.

4. Ceramic forming techniques - Wikipedia

   en.wikipedia.org/wiki/Ceramic_forming_techniques

   Ceramic shell casting techniques using silica, zirconia and other refractory materials are currently used by the metal parts industry for 'net casting', forming precision shell moulds for molten metal casting. The technique involves a successive wet dipping and dry powder coating or stucco to build up the mould shell layer.

5. Wah Chang Corporation - Wikipedia

   en.wikipedia.org/wiki/Wah_Chang_Corporation

   Wah Chang Corporation was an American manufacturing company in the metal or alloy industry based in Albany, Oregon in the United States. Since 2014, it has been a business unit of Allegheny Technologies and makes corrosion-resistant metals, such as hafnium, niobium, titanium, vanadium, and zirconium.

6. Zirconium dioxide - Wikipedia

   en.wikipedia.org/wiki/Zirconium_dioxide

   Zirconia is also employed in the deposition of optical coatings; it is a high-index material usable from the near-UV to the mid-IR, due to its low absorption in this spectral region. In such applications, it is typically deposited by PVD. [23] In jewelry making, some watch cases are advertised as being "black zirconium oxide". [24]

7. Diamond simulant - Wikipedia

   en.wikipedia.org/wiki/Diamond_simulant

   Cubic zirconia can be coated with diamond-like carbon to improve its durability, but will still be detected as CZ by a thermal probe. CZ had virtually no competition until the 1998 introduction of moissanite (SiC; silicon carbide). Moissanite is superior to cubic zirconia in two ways: its hardness (8.5–9.25) and low SG (3.2).

9. Zirconium silicon sulfide - Wikipedia

   en.wikipedia.org/wiki/Zirconium_silicon_sulfide

   Zirconium silicon sulfide (ZrSiS) is a crystalline layered Dirac semi-metal compound of zirconium, silicon and sulfur. [1] Its crystals are made from planes of five single-atom layers of each element in the order S-Zr-Si-Zr-S, with the single element planes connected to their neighbors by van der Waals forces .
