Is titanium gevaarlijk?
Titaniumdioxide zit in verschillende consumentenproducten, zoals voedsel, verf en zonnebrandcrème. Mensen die dit soort producten maken, kunnen titaniumdioxide deeltjes inademen tijdens hun werk. Iedereen kan titaniumdioxide deeltjes inslikken via voedsel of medicijnen.
Iedereen kan titaniumdioxide deeltjes inslikken via voedsel of medicijnen. Er is al jarenlang discussie over de veiligheid van titaniumdioxide. De deeltjes zijn mogelijk kankerverwekkend na inademing. Of ze ook kanker kunnen veroorzaken na inslikken is onzeker.
Is titaniumdioxide giftig?
Titaniumdioxide kan namelijk niet via de huid in het lichaam terechtkomen. Titaniumdioxide is wel verdacht kankerverwekkend. als je het inademt. Het gaat hierbij om poedervormig titaniumdioxide dat 1% of meer deeltjes bevat die kleiner zijn dan 10 micrometer.
Why does titanium dioxide have a low refractive index?
It is common to find titanium dioxide paired with silicon dioxide (SiO2) as the low refractive index material. TiO2’s index can vary due to density variations caused by different deposition processes.
Is photoinduced discoloration of mixtures of titanium dioxide and silver nitrate possible?
An infrared study has been made of the photoinduced discoloration of mixtures of titanium dioxide and silver nitrate. Attenuated total reflectance and conventional transmission measurements have been made on samples before and after exposure to ultraviolet radiation.
What is the reflectance of TiO2 in Nir?
TiO2nanostructures synthesized at 74 A arc current show diffuse reflectance from 49 % to 45 % in the NIR range (700 – 2500 nm). ZnO nanostructures show diffuse reflectance from 57 % to 14 % in the NIR range (700 – 2500 nm).

Why is TiO2 used in thin-film optics?
Titanium dioxide (TiO2) is well-known for having a very high index of refraction, and this has led to its common use in thin-film optics. Typically, TiO2 is one component of alternating layers of high and low refractive index materials that by the principle of optical interference tailor the thin-film optic’s spectral reflectance profile.
