  2. Zirconium dioxide - Wikipedia

    en.wikipedia.org/wiki/Zirconium_dioxide

    Zirconium dioxide (ZrO. 2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite. A dopant [clarification needed] stabilized cubic structured zirconia, cubic zirconia, is synthesized in ...

  3. Zirconocene - Wikipedia

    en.wikipedia.org/wiki/Zirconocene

    Zirconocene is a hypothetical compound with 14 valence electrons, which has not been observed or isolated. It is an organometallic compound consisting of two cyclopentadienyl rings bound on a central zirconium atom. A crucial question in research is what kind of ligands can be used to stabilize the Cp 2 Zr II metallocene fragment to make it ...

  4. Zirconium - Wikipedia

    en.wikipedia.org/wiki/Zirconium

    Zirconium is a chemical element; it has symbol Zr and atomic number 40. First identified in 1789, isolated in impure form in 1824, and manufactured at scale by 1925, pure zirconium is a lustrous transition metal with a greyish-white color that closely resembles hafnium and, to a lesser extent, titanium. It is solid at room temperature, ductile ...

  5. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    Molecular orbital diagram of NO. Nitric oxide is a heteronuclear molecule that exhibits mixing. The construction of its MO diagram is the same as for the homonuclear molecules. It has a bond order of 2.5 and is a paramagnetic molecule. The energy differences of the 2s orbitals are different enough that each produces its own non-bonding σ orbitals.

  6. Zirconium(IV) silicate - Wikipedia

    en.wikipedia.org/wiki/Zirconium(IV)_silicate

    Zirconium silicate, also zirconium orthosilicate, ZrSiO 4, is a chemical compound, a silicate of zirconium. It occurs in nature as zircon, a silicate mineral. Powdered zirconium silicate is also known as zircon flour. Zirconium silicate is usually colorless, but impurities induce various colorations. It is insoluble in water, acids, alkali and ...

  7. Electron configuration - Wikipedia

    en.wikipedia.org/wiki/Electron_configuration

    Electron configuration. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s2 2s2 2p6, meaning that the 1s, 2s, and 2p subshells are occupied by ...

  8. Zirconium diboride - Wikipedia

    en.wikipedia.org/wiki/Zirconium_diboride

    Zirconium diboride (ZrB 2) is a highly covalent refractory ceramic material with a hexagonal crystal structure. ZrB 2 is an ultra-high temperature ceramic (UHTC) with a melting point of 3246 °C. This along with its relatively low density of ~6.09 g/cm 3 (measured density may be higher due to hafnium impurities) and good high temperature ...

  9. 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.
