Titanium Oxide vs. Titanium Dioxide: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 4, 2023
Titanium oxide refers to various titanium-oxygen compounds, while titanium dioxide, specifically TiO2, is a widely used white pigment.
Key Differences
Titanium oxide encompasses a range of titanium-oxygen compounds with varying oxygen levels. However, titanium dioxide, or TiO2, is a specific type of titanium oxide with a fixed ratio of one titanium atom to two oxygen atoms.
In terms of chemical properties, titanium oxide compounds can differ widely. Titanium dioxide is well-known for its high stability, refractive index, and pigment properties.
Titanium oxide is used in various applications depending on its composition. Titanium dioxide is extensively used in paints, coatings, and as a UV filter in sunscreens.
The preparation and processing of titanium oxide can vary based on the desired oxide. Titanium dioxide is often produced by the sulfate process or the chloride process.
Some forms of titanium oxide are studied for photocatalytic activities. Titanium dioxide, in particular, is researched for its ability to degrade pollutants under UV light.
