On Zirconia
Posted : admin On 4/9/2022Features
Zirconia has been the most investigated and used among the metal oxide-based stationary phases. Columns packed with zirconia manufactured by ZirChrom are now commercially available also in sub. In most cases, cubic zirconia loose stones are sold in lots. Each lot will have an approximate size range, usually measured in millimeters. And typically, each lot will contain stones of the same cut. An independent endorsement standing for Swarovski’s enduring commitment to the highest standards of excellence since 1895. The use of the special 'Zirconia from Swarovski' seal is a strong symbol of identification for the products of Swarovski Partners, enhancing their value and providing assurance that you are buying only the finest zirconia. 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.
Zirconia has excellent mechanical properties, with higher strength and fracture toughness than alumina.
It is also used in milling machines, sliding parts and cutting blades.
Zirconia exhibits great heat insulation, as its thermal conductivity is less than 1/10 that of other ceramics.

PRECISION MACHINED PRODUCTS
Ultra-precision is possible with Kyocera's unique techniques.
Precision machining is affected by shape and material.
Some practical examples are shown in the table below.
* Surface roughness depends on the material. The data shown here indicates where alumina is used.
