TiO₂ rutile-type nano titanium dioxide provides optimized UV absorption, superior photocatalytic efficiency, and enhanced thermal stability. Designed for coatings, environmental purification, and electronic applications, it ensures effective light absorption, extended durability, and high adaptability.
Product Overview
Titanium dioxide (TiO₂) is a critical white inorganic pigment widely used in coatings, plastics, paper, inks, and various other industries. Titanium dioxide comes in two crystalline structures: rutile and anatase, with rutile offering excellent optical and chemical properties. It appears as a white solid or powder, has a high refractive index, and provides outstanding opacity. It demonstrates high chemical stability under normal conditions, with good resistance to acids, bases, and other chemicals. It is amphoteric, showing different chemical behaviors in various acidic and alkaline environments.
Product Features
- Excellent Opacity: Provides superior covering power, making it ideal for use in coatings and cosmetics.
- High Hardness: Mohs hardness of 6 - 7, suitable for applications requiring abrasion resistance.
- High Melting Point: With a melting point of 1843°C, it maintains stability under high temperatures.
- Good Stability: Chemically stable at room temperature and resistant to water, acids (except concentrated sulfuric acid), and bases.
- Amphoteric Nature: Exhibits both acidic and basic oxide properties, showing varied chemical behavior in different acid-base environments.
- Strong UV Absorption: Absorbs ultraviolet light, particularly in the 380 - 400nm range, making it effective for sunscreen and UV-protective products.
Applications
Titanium dioxide finds widespread application across several industries:
- Coatings Industry: Provides excellent whiteness and brightness, extensively used in all types of paints and coatings.
- Plastics Industry: Enhances opacity and durability in plastics.
- Paper Industry: Used as a white pigment to improve the brightness of paper.
- Cosmetics Industry: Due to its excellent opacity and UV absorption, it is used in sunscreen and other UV-protective products.
- Ceramics Industry: Used in ceramic coatings and glazes.
- Electronics Industry: Utilized in dielectric materials such as multi-layer ceramic capacitors, disc capacitors, and positive temperature coefficient thermistors.
- Optical Industry: Applied in the production of optical glass and coatings.
