The behavior of the anodic films on titanium and zirconium in H3PO4

The great efforts devoted to the research on titanium oxide material produced many promising uses in areas that range from photovoltaics and photocatalysis to photo-electrochromic and sensors. These uses can be generally classified into energy and environmental types many types rely not only on the properties of the titanium oxide material itself but also on the changes in the oxide host. Zirconium compounds are used in many biomedical applications including dental implants knee and hip replacements middle-ear ossicular chain reconstruction and other restorative and prosthetic devices. Because of the low thermal neutron capture cross-section adequate mechanical properties and good corrosion resistance zirconium and its alloys are used in the nuclear industry. For example it can serve as fuel cladding and core structure material. Therefore titanium zirconium and their oxides are very important in the electronic industries.
