Zirconium Oxide


The outstanding properties of zirconium oxide materials are due to the stabilizing additives of yttria and magnesia. Zirconium oxide has a very fine grain structure which leads to very high toughness and mechanical strength.


Extraordinary toughness

The cross-linked microstructure of our silicon nitride material allows for very high thermal shock resistance as compared to other advanced ceramic materials.


Solid Mechanical Strength

Materials offer very high mechanical strength at low-temperature applications.


Good Corrosion resistance

Materials are ideal for medical and other selected wear applications
