Question

________is the property of titania.

• A. Stability against ultraviolet radiation
• B. High fracture toughness
• C. High modulus of rupture
• D. High compressive strength

Hint:

Titanium dioxide (TiO\(_2\)) is widely used in paints, sunscreens, and photocatalysis due to its UV-resistant and optical properties.

Answer 1

The Correct Option is A

Titania, also known as titanium dioxide (TiO\(_2\)), is a widely used ceramic material known for its unique optical and chemical properties.
Step 1: Understanding the Properties of Titania - Stability against ultraviolet (UV) radiation: Titania is a UV-resistant material used in sunscreens, paints, and coatings due to its excellent ability to absorb and scatter UV rays.
- Fracture toughness: Titania does not exhibit high fracture toughness, as it is a brittle ceramic.
- Modulus of rupture: Though it has decent strength, its modulus of rupture is not its defining characteristic.
- Compressive strength: While titania has some mechanical strength, its primary use is in optical, photocatalytic, and protective applications.


Step 2: Evaluating the Options - Option (A) - Correct: Titania is highly stable against ultraviolet radiation, making it useful in coatings and sunscreens.
- Option (B) - Incorrect: Titania does not have high fracture toughness.
- Option (C) - Incorrect: The modulus of rupture is not its key property.
- Option (D) - Incorrect: Titania is not known for its high compressive strength.


Step 3: Conclusion Since Titania is highly stable against ultraviolet radiation, the correct answer is option (A).
