About the chemical structure:

Chemical name: Titanium dioxide
Formula: TiO2
3D model:

Crystal structure of anatase

Crystal structure of rutile

grey = titanium, red = oxygen

Refractive index: anatase: 2.3 - 2.65


Color Index (C.I.) PW 6

How can you identify Titanium white?


UVF: no

OM: Microcrystalline in nature with fine particles. Very fine pseudo-opaque but generally colour less crystals. Often rounded rhomboids. The crystals are so small that they often appear cream to a light brown opaque colour under normal incident light on the microscope. Particles are usually up to 1μm in size.

Microscopic appearance at x500 mag


It's identified by means of FTIR and Raman.

Raman spectra: ColoRaman

FTIR spectra: IRUG



Usage and handling:

Permanence: Toxicity:

Lightfast: excellent.

Degradation processes: unaffected by dilute alkali's, acids, light and air. Non-reactive with drying oils and therefore has avery slow drying time. High oil absorbing nature.

Non toxic.

MSDS: Kremer
