Titanium Dioxide, titanium(IV) oxide, titania
Titanium dioxide (TiO2), more commonly known as titania, is a white crystalline substance that is used as a pigment additive, a UV adsorbent and a photocatalyst. It is also used in new, advanced electronic circuitry. Titanium oxide is a relatively hard material with moderate thermal conductivity and a very high refractive index. It can be used as a catalyst or as a catalyst carrier. Titania is photocatalytic and non-toxic. MemPro’s titanium oxide nanofibers - in the family of nCeramic materials - are available with narrow fiber diameter distributions (ave. 100 – 120 nm).
