Description
Titanium Dioxide (TiO₂) Micron Powder, Purity: 99.5 %, Size: 1–3 µm, White, Rutile
Product Description:
Titanium Dioxide (TiO₂) Micron Powder is a high-purity, fine white powder in the rutile crystalline phase, offering excellent optical, chemical, and thermal properties. With 99.5% purity and a particle size range of 1–3 µm, this form of TiO₂ is widely used in coatings, pigments, paints, inks, and cosmetic formulations due to its high refractive index, strong UV absorption capability, and superior brightness.
Rutile TiO₂ is thermodynamically more stable than the anatase form and exhibits greater resistance to heat, light, and chemicals, making it the preferred choice in industrial and high-durability coatings, powder coatings, and medical-grade pigments.

Why Rutile TiO₂?
The rutile phase exhibits higher density and lower photoreactivity than the anatase phase, making it ideal for UV protection, durability, and chemical stability. It remains a staple for both functional and decorative applications.
