MSE PRO Titanium Dioxide Sputtering Target TiO2
Titanium Dioxide (TiO2) Material Information
To add a Cu Backing Plate with Indium Bonding for Sputtering Targets 
Titanium dioxide (TiO2) is the most widely used white pigment, for example in paints. It has high brightness and a very high refractive index (2.609 for rutile). The light passes through the crystal slowly and its path is substantially altered compared to air. If you have many small particles orientated in different directions, a high refractive index will lead to the scattering of light as not much light passes through. In lenses, high refractive index means high clarity and high polarizing power.
Titanium dioxide has a higher refractive index than diamond and there are only a few other substances that have a higher refractive index.
When deposited as a thin film, its refractive index and color make it an excellent reflective optical coating for dielectric mirrors; it is also used in generating decorative thin films such as found in "mystic fire topaz".
