  2. Zirconium - Wikipedia

    en.wikipedia.org/wiki/Zirconium

    Zirconium is a lustrous, greyish-white, soft, ductile, malleable metal that is solid at room temperature, though it is hard and brittle at lesser purities. [12] In powder form, zirconium is highly flammable, but the solid form is much less prone to ignition. Zirconium is highly resistant to corrosion by alkalis, acids, salt water and other ...

  3. Zircon - Wikipedia

    en.wikipedia.org/wiki/Zircon

    Zircon (/ ˈ z ɜːr k ɒ n,-k ən /) [7] [8] [9] is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium. Its chemical name is zirconium(IV) silicate, and its corresponding chemical formula is Zr SiO 4. An empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x ...

  4. Cubic zirconia - Wikipedia

    en.wikipedia.org/wiki/Cubic_zirconia

    Cubic zirconia (abbreviated CZ) is the cubic crystalline form of zirconium dioxide (ZrO 2). The synthesized material is hard and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO 4). It is sometimes erroneously called cubic zirconium.

  5. 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.

  6. 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.
