Ideal for applications that must resist bending and wear as well as carry heavy loads, these rods and discs are often used for sleeve bearings and shafts instead of metal. Added yttria gives this material more strength and lowers the chances of cracking from impact compared to standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of this material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.

Zirconia ceramic resists bending better than alumina and silicon nitride ceramic but does not withstand rapid temperature changes or high temperatures as well as other high-performance ceramics.
