Powerful interatomic bonds endows zirconia ceramics not only with high hardness and wear resistance, but also a resistance to corrosion. Usually it has less hardness and brittleness than that of alumina ceramic, but has more elasticity, which means it is not as brittle as alumina ceramic. If hardness is not so exacting, zirconia parts are a good choice to be applied.
