TiO₂ rutile-anatase mixed crystal titanium dioxide provides optimized photocatalytic activity, superior light absorption, and enhanced stability. Designed for coatings, solar cells, and environmental applications, it ensures efficient charge transfer, extended durability, and high adaptability.
Product Overview
Titanium dioxide (TiO₂) is an important white inorganic pigment widely used in industries such as coatings, plastics, paper, and inks. It exists in two primary crystalline structures: rutile and anatase, with rutile offering superior stability and optical performance. Titanium dioxide appears as a white solid or powder and has a high refractive index, providing excellent opacity. It exhibits exceptional chemical stability under normal conditions and is resistant to acids, bases, and other chemicals.
Product Features
- Excellent Opacity: Offers outstanding covering power, widely used in coatings and cosmetics.
- High Hardness: With a Mohs hardness of 6 - 7, it is suitable for applications requiring abrasion resistance.
- High Melting Point: With a melting point of 1843°C, it remains stable under high-temperature conditions.
- Good Stability: Chemically stable under normal conditions, with minimal reaction to water, acids (except concentrated sulfuric acid), and bases.
- Amphoteric Nature: Exhibits both acidic and basic oxide properties, showing different chemical behaviors in various acidic and alkaline environments.
- Strong UV Absorption: Exhibits strong absorption of ultraviolet light, especially in the 380 - 400nm range, making it suitable for sunscreen products and UV-blocking materials.
Applications
Titanium dioxide is widely used in various industries:
- Coatings Industry: Provides excellent whiteness and brightness, extensively used in all types of paints and coatings.
- Plastic Industry: Used to improve the opacity and durability of plastics.
- Paper Industry: Used as a white pigment to enhance the brightness of paper.
- Cosmetics Industry: Due to its excellent opacity and UV absorption properties, it is widely used in sunscreens and other UV-protective products.
- Ceramic Industry: Used in ceramic coatings and glazes.
- Electronics Industry: Used in dielectric materials like multi-layer ceramic capacitors, disc capacitors, and positive temperature coefficient thermistors.
