PHARMAZIRC®
Its carefully controlled chemistry and microstructure imparts excellent resistance to corrosion by both acid and alkali cleaning solutions and to the hydro-thermal destabilization that happens with other zirconia ceramics during steam sterilization.
This material is also non-cytotoxic and does not release particles. It is easy to clean due to the low porosity. It has high wear resistance, a low friction coefficient and accepts highly smooth surface finishing as a result of its very fine grain size and low porosity.
