A nice walk in the region of Oviedo. Zirconium oxides are available in numerous forms such as powder and dense pellets for such uses as optical coating and thin film applications. Zirconium (Zr), in particular, is in fact one of the two most commonly used metals in dental implants, alongside titanium, as they both show very good physical and chemical properties and they allow the growth of osteoblasts, the cells that actually form bones [3]. The desired properties of these alloys are a low neutron-capture cross-section and resistance to corrosion under normal service conditions.
