  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. 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.

  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 ...

  6. Organozirconium and organohafnium chemistry - Wikipedia

    en.wikipedia.org/wiki/Organozirconium_and_organo...

    Organozirconium chemistry is the science of exploring the properties, structure, and reactivity of organozirconium compounds, which are organometallic compounds containing chemical bonds between carbon and zirconium. [2] Organozirconium compounds have been widely studied, in part because they are useful catalysts in Ziegler-Natta polymerization.

  7. Zirconocene dichloride - Wikipedia

    en.wikipedia.org/wiki/Zirconocene_dichloride

    Zirconocene dichloride reacts with lithium aluminium hydride to give Cp 2 ZrHCl Schwartz's reagent: (C 5 H 5) 2 ZrCl 2 + 1 / 4 LiAlH 4 → (C 5 H 5) 2 ZrHCl + 1 / 4 LiAlCl 4. Since lithium aluminium hydride is a strong reductant, some over-reduction occurs to give the dihydrido complex, Cp 2 ZrH 2; treatment of the product mixture with methylene chloride converts it to Schwartz's reagent.

  8. Baddeleyite - Wikipedia

    en.wikipedia.org/wiki/Baddeleyite

    Baddeleyite is a rare zirconium oxide mineral (ZrO 2 or zirconia), occurring in a variety of monoclinic prismatic crystal forms. It is transparent to translucent, has high indices of refraction, and ranges from colorless to yellow, green, and dark brown.

  9. Ultra-high temperature ceramic - Wikipedia

    en.wikipedia.org/wiki/Ultra-high_temperature_ceramic

    Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.
