Technical Information
Our Titanium oxide (TiO2 , anatase) nanoparticles portfolio consist of particles with diameters ranging from 5 to 15 nanometers and find applications in several industries.
TiO2 nanoparticles with sizes below 20 nm display UV absorption behavior without light scattering and they are extensively employed as inorganic UV filter. The advantage of using monodisperse nanoparticles is better understood when we think that scattering phenomena are largely size dependent: a broad distribution of nanoparticles will increase the probability of light scattering phenomena, limiting the transparency of a coating.
In order to be able to take advantage of the various properties of Titanium Oxide (TiO2) nanoparticles, significant care needs to be taken in controlling size, monodispersity and crystalline structure.
We at Particular Materials synthesize and supply TiO2 nanoparticles and we produce nanodispersions in water and in organic solvents, with excellent stability, monodispersity, crystalline purity and fully disaggregated state.
The TiO2 nanoparticles are available in two different sizes:
- 4.8 ± 0.9 nm
- 15.2 ± 3.5 nm
Typical concentration in water are, by weight (w/w%):
- 1%
- 5%
- 10%
- 20%
TiO2 can also be provided as nanopowder.
