How does anatase titanium dioxide differ from rutile?

Anatase and rutile are both crystal forms of titanium dioxide under CAS 13463-67-7. Anatase has a density around 3.8-3.9 g/cm³ and refractive index about 2.55, while rutile is denser with a refractive index near 2.7. Anatase is softer and tends to give higher whiteness with a slight blue tone, but rutile provides better weathering resistance.

What are the main applications of anatase titanium dioxide?

Anatase titanium dioxide is used in indoor coatings, paper, plastics, fibers, printing inks, ceramics, rubber, and specialized photocatalytic applications. It provides high brightness, hiding power, and tinting strength where long-term exterior weather resistance is not the main requirement.

Is this grade suitable for exterior coatings?

Anatase has higher photocatalytic activity than rutile, so it can promote chalking or surface degradation during prolonged outdoor exposure. For exterior architectural or industrial coatings, rutile or a suitably surface-treated grade is usually the better choice.

What specifications should be checked before ordering?

Confirm TiO₂ content, crystal form, whiteness, tinting strength, oil absorption, particle size, moisture or volatile matter, loss on ignition, and residue on sieve. Also clarify any surface treatment and the target coating, plastic, paper, or specialty application, because different grades are optimized differently.

How should anatase titanium dioxide be stored and handled?

Store it in tightly closed bags or containers in a cool, dry, well-ventilated area away from moisture and incompatible materials. Avoid generating airborne dust, use local exhaust or dust control during bulk handling, and keep packages sealed between uses to prevent caking and contamination.

Product Description

Anatase Titanium Dioxide, CAS 13463-67-7, also known as titania or titanium(IV) oxide, is a high-whiteness inorganic pigment in the anatase crystal form; the EC/EINECS number is 236-675-5.

Synonyms: titanium(IV) oxide; titania; C.I. Pigment White 6; titanium peroxide; titanium white.

CAS: 13463-67-7.

Molecular formula: TiO₂.

Molecular weight: 79.87.

EC number: 236-675-5.

It is a white fine powder with a TiO₂ content typically ≥98.0%, whiteness ≥96% and tinting strength ≥100%.

The specific gravity is 3.8–3.9 g/cm³, the refractive index about 2.55 and the oil absorption about 23–28 g/100 g.

A 10% aqueous suspension typically has a pH of 6.5–8.0; volatile matter, moisture and loss on ignition are each typically ≤0.5%, and residue on a 45 µm sieve is ≤0.05%.

It is used as a white pigment in interior wall paints, primers, putties, and water-based or solvent-based industrial coatings.

It is used in paper, plastics, fibers, printing inks, ceramics and rubber for brightness, hiding power and tinting strength.

It is also used in specialized photocatalytic applications; anatase has higher photocatalytic activity than rutile, so rutile or surface-treated grades are preferred for exterior coatings.

Confirm TiO₂ content, crystal form, whiteness, tinting strength, oil absorption, particle size, moisture, loss on ignition, residue on sieve and any surface treatment.

Store in tightly closed bags in a cool, dry, well-ventilated area away from moisture; use dust control or local exhaust during bulk handling and keep packages sealed between uses.
