  2. Zirconium dioxide - Wikipedia

    en.wikipedia.org/wiki/Zirconium_dioxide

    Zirconium dioxide (ZrO 2 ), sometimes known as zirconia (not to be confused with zirconium silicate or zircon ), is a white crystalline oxide of zirconium . Its most naturally occurring form, with a monoclinic crystalline structure , is the mineral baddeleyite .

  3. Zirconium - Wikipedia

    en.wikipedia.org/wiki/Zirconium

    Zirconium also finds uses in flashbulbs, biomedical applications such as dental implants and prosthetics, deodorant, and water purification systems. Zirconium compounds have no known biological role, though the element is widely distributed in nature and appears in small quantities in biological systems without adverse effects.

  4. Cubic zirconia - Wikipedia

    en.wikipedia.org/wiki/Cubic_zirconia

    Discovered in 1892, the yellowish monoclinic mineral baddeleyite is a natural form of zirconium oxide. [2] The high melting point of zirconia (2750 °C or 4976 °F) hinders controlled growth of single crystals. However, stabilization of cubic zirconium oxide had been realized early on, with the synthetic product stabilized zirconia introduced ...

  5. Yttria-stabilized zirconia - Wikipedia

    en.wikipedia.org/wiki/Yttria-stabilized_zirconia

    Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" (Zr O 2) and "yttria" (Y 2 O 3), hence the name.

  6. Zirconia toughened alumina - Wikipedia

    en.wikipedia.org/wiki/Zirconia_Toughened_Alumina

    Zirconia aluminia (or zirconia toughened alumina), a combination of zirconium oxide and aluminum oxide, is part of a class of composite ceramics called AZ composites. Noted for their mechanical properties, AZ composites are commonly used in structural applications, as cutting tools, and in many medical applications.

  7. Ceria-zirconia - Wikipedia

    en.wikipedia.org/wiki/Ceria-zirconia

    Ceria-zirconia is widely used as a component in current three-way catalytic converters. [6] The ceria-based component of the converter has several functions, including promoting the dispersion of the noble metals in the catalyst, but also storing and releasing oxygen. [7]

  8. 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.

  9. Ceramic knife - Wikipedia

    en.wikipedia.org/wiki/Ceramic_knife

    A ceramic knife is a knife with a ceramic blade typically made from zirconium dioxide (ZrO 2; also known as zirconia), [1] rather than the steel used for most knives. Ceramic knife blades are usually produced through the dry-pressing and firing of powdered zirconia using solid-state sintering .
