Key Differences
General Terminology: Titanium Oxide is a broader term, encompassing various oxides of titanium with different oxygen content. Conversely, Titanium Dioxide refers to a specific compound with the formula TiO₂.
Chemical Composition: While Titanium Oxide can denote any oxide of titanium, Titanium Dioxide is a particular compound wherein every titanium atom is paired with two oxygen atoms. It's essential to understand that Titanium Dioxide is a type of Titanium Oxide, but not every Titanium Oxide is Titanium Dioxide.
Applications: Titanium Oxide, as a general term, doesn't pinpoint a specific use since it can relate to different compounds. In contrast, Titanium Dioxide is widely used in industries such as paints, cosmetics, and sunscreens due to its bright whiteness and UV-resistant properties.
Physical Properties: Titanium Dioxide is recognized for its white pigment and is a powdery solid. Depending on the specific type and oxidation state, Titanium Oxides might vary in appearance and properties.
Occurrence: Titanium Dioxide occurs naturally in several minerals. Titanium Oxide, being a more generic term, may refer to multiple naturally occurring or synthetically produced compounds.
