Zirconia (Zirconium Oxide, ZrO2)
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.
Dimensional precision achieved by machining
When dimensional precision is required for machined ceramics, Kyocera is capable of achieving the tolerances as shown in the table below. If greater tolerances are required, please consult us.

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.
* The values are typical material properties and may vary according to products configuration and manufacturing process. For more details, Please feel free to contact us.
* 1: All values for apparent density and bulk density are the same, except for A482R which lists apparent density only.
