High hardness. Wear resistance. Use temperatures up to 2400º C. High fracture toughness. Zirconium dioxide (ZrO2) commonly known as Zirconia, is a natural occurring metal with a monoclinic crystalline structure. It has same features and design as that of alumina, but gives better finish after surface grinding as compared to alumina.
A ceramic knife is a knife designed with a ceramic blade typically made from zirconium dioxide (ZrO 2; also known as zirconia). These knife blades are usually produced through the dry-pressing and firing of powdered zirconia using solid-state sintering.It is 8.5 on the Mohs scale of mineral hardness, compared to 4.5 for normal steel and 7.5 to 8 for hardened steel and 10 for diamond.
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.
The dental zirconia is zirconium dioxide (ZrO 2), which is a powdered form of zirconium. Since the 1990s, zirconia is used for endodontic posts and implants. (Endodontic post helps you retain your restorations and fillings as well as crowns.) Zirconia crowns are the strongest dental crowns.
Zirconium dioxide (ZrO 2), which is also referred to as zirconium oxide or zirconia, is an inorganic metal oxide that is mainly used in ceramic materials. Zirconium dioxide succeeds zirconium as the compound of the element zirconium that most frequently occurs in nature.
Apr 25, 2018· Zirconia Crowns: What They Are, How They're Made Zirconia (zirconium dioxide) is a white, powdered metal oxide. It is a ceramic, such as other general dental crown materials. Zirconia is produced from zirconium, a metal with similar properties to titanium. Zirconium is chemically un-reactive and it as well makes a good choice for the dental...

Learn about product material, Zirconia (Zirconium Oxide, ZrO2). is the global leading manufacturer of superior precision Fine Ceramics (Advanced Ceramics).
Zircon (/ ˈ z ɜːr k ɒ n / or / ˈ z ɜːr k ən /) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate, and its corresponding chemical formula is Zr SiO 4. A common empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x (OH) 4x–y.
The oxide ceramic zirconium oxide, or zirconia (ZrO2) is a ceramic material with very high crack propagation resistance and thermal expansion. These properties are the reason why zirconium oxide ceramics from CeramTec are chosen to join ceramic and steel.
Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zar-gun, "gold-like" or "as gold")), the most important source of zirconium.
It is normally used in the form of zirconium silicate. It is beneficial to add zircon to transparent glazes in amounts up to 3% to improve hardness and duravility. This is because small amounts can be taken into solution and will therefore not opacify.
Cubic zirconia (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.. Because of its low cost, durability, and close visual likeness to diamond ...
Cubic Zirconia vs Diamond comparison. Although very different in other properties, cubic zirconia and diamond appear similar to a lay person because of their outer appearance and high refractive index. Fact is, diamond is a very expensive, naturally occurring substance, whereas cubic zirconia...
Zirconium Alloy Data Sheet Description Zirconium is used in services too severe for stainless steels, nickel alloys, and titanium or where a significant improvement in service life can be achieved by choosing zirconium instead of less expensive metals or plastics.
Zirconium Dioxide or zirconia (ZrO 2) is a metallic oxide either processed from the mineral Baddeleyite (zirconium oxide) or extracted from zirconium silicate sand.While there is an abundance of raw material (mostly from Australia and South Africa), processes to extract the ZrO 2 are varied and expensive (e.g. fusing, leaching, plasma arc, dissolution and precipitation).
Zirconium dioxide or zirconia is one of the most widely used ceramic oxides. Its applications range from use in abrasive products, dental bridges and crowns, additive in paints and lacquers, in fuel cell membranes and in joint implants.

For years, tests have concluded that high-performance coatings provide excellent corrosion protection and durability when applied over a blast-cleaned surface with a consistent anchor profile.
Zirconium dioxide (zirconia) is produced by heating zircon sand to a high enough temperature to break down the zircon molecule. In powdered form, zirconium dioxide is bright white, highly reflective and thermally stable. It is used as an opacifier, whitening agent, and pigment in glazes and stains used on ceramics and pottery.
