2. 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 ...

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. 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 ...

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. Tetragonal polycrystalline zirconia - Wikipedia

   en.wikipedia.org/wiki/Tetragonal_polycrystalline...

   Yttria blends of approximately 3% are called either tetragonal polycrystalline zirconia or tetragonal zirconia polycrystal (forming the initialisms TZP or TPZ) and have the finest grain size. These grades exhibit the highest toughness at room temperature, because they are nearly 100% tetragonal, but this degrades severely between 200 and 500 ...

7. 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.

8. Yttrium(III) oxide - Wikipedia

   en.wikipedia.org/wiki/Yttrium(III)_oxide

   Yttrium oxide is used to stabilize the Zirconia in late-generation porcelain-free metal-free dental ceramics. This is a very hard ceramic used as a strong base material in some full ceramic restorations. [9] The zirconia used in dentistry is zirconium oxide which has been stabilized with the addition of yttrium oxide. The full name of zirconia ...
