2. Zirconium dioxide - Wikipedia

   en.wikipedia.org/wiki/Zirconium_dioxide

   [11] [12] [13] Zirconia stabilized with yttria (yttrium oxide), known as yttria-stabilized zirconia, can be used as a strong base material in some full ceramic crown restorations. [12] [14] Transformation-toughened zirconia is used to make ceramic knives. [15] Because of the hardness, ceramic-edged cutlery stays sharp longer than steel edged ...

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. Zirconia toughened alumina - Wikipedia

   en.wikipedia.org/wiki/Zirconia_Toughened_Alumina

   It is a composite ceramic material with zirconia grains in the alumina matrix. It is also known in industry as ZTA. 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 ...

5. Zirconium - Wikipedia

   en.wikipedia.org/wiki/Zirconium

   Zirconium dioxide (ZrO 2) is used in laboratory crucibles, in metallurgical furnaces, and as a refractory material [13] Because it is mechanically strong and flexible, it can be sintered into ceramic knives and other blades. [51] Zircon (ZrSiO 4) and cubic zirconia (ZrO 2) are cut into gemstones for use in jewelry.

6. 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.

7. Ceramic - Wikipedia

   en.wikipedia.org/wiki/Ceramic

   Ceramic material is an inorganic, metallic oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand the chemical erosion that occurs in other materials subjected to acidic or caustic ...

8. Crown (dental restoration) - Wikipedia

   en.wikipedia.org/wiki/Crown_(dental_restoration)

   Yttria-stabilized zirconia, also known simply as zirconia, is a very hard ceramic that is used as a strong base material in some full ceramic restorations. Zirconia is relatively new in dentistry and the published clinical data is correspondingly limited.

9. Ceramography - Wikipedia

   en.wikipedia.org/wiki/Ceramography

   The toughness of most ceramics is 2–4 MPa √ m, but toughened zirconia is as much as 13, and cemented carbides are often over 20. [15] The toughness-by-indention methods have been discredited recently and are being replaced by more rigorous methods that measure crack growth in a notched beam in bending.
