Definition
Noun: - A white, inorganic compound, primarily titanium dioxide (TiO₂), used extensively as a white pigment due to its exceptional opacity, brightness, and resistance to degradation.
Usage
- This term refers specifically to the compound in its use as a pigment or industrial material. It is a technical term common in chemistry, manufacturing, and art conservation contexts.
- Example: "The brilliant white of the paint was achieved by using titanic oxide as the primary pigment."
- Example: "Due to its high covering power, titanic oxide is a key ingredient in sunscreens and plastics."
Advanced Usage
- In scientific literature, "titanic oxide" is often synonymous with the more modern term titanium dioxide. It may be specified in different crystalline forms (e.g., rutile, anatase) which affect its properties.
- Example: "The study compared the photocatalytic activity of rutile versus anatase forms of titanic oxide."
