Yttria Tetragonal Zirconia Polycrystal (Y-TZP) …
Yttrium oxide is used as the stabiliser. This material is predominantly tetragonal in structure. Y-TZP has the highest flexural strength of all the zirconia based materials, particularly when HIPed. The fine grain size of Y-TZP lends itself to be used in cutting tools where a very sharp edge can be achieved and maintained due to its high wear resistance.
The fine grade size leads to a very dense, non porous ceramic with excellent mechanical strength, corrosion resistance, impact toughness, thermal shock resistance and very low thermal conductivity. Due to its characteristics Y-TZP is used in wear parts, cutting tools and thermal barrier coatings.
