Chemical Stability
- Acid/Alkali Resistance	Stable at room temperature. Reacts with strong acids (e.g., H2SO4) or alkalis (e.g., molten NaOH) at high temperatures.
- Photocatalytic Activity	Anatase type decomposes organic compounds under UV light-used in air purification and antibacterial coatings.
- Redox Properties	Can be reduced to lower titanium oxides (e.g., Ti3O5) at high temperatures by carbon or aluminum.
Optical Properties
- Refractive Index	2.4-2.7 (provides excellent opacity and whiteness, ideal for white pigments).
- UV Absorption	Absorbs UVA (320-400 nm) and UVB (280-320 nm)-widely used in sunscreens.

 

Application Guide

 
 1. Coatings & Inks
TiO2 is a key component in coatings and inks for its superior hiding power, anti-degradation performance, and weathering resistance. Applied in architectural paints (e.g., exterior wall finishes), automotive coatings, and marine protective layers, its high light-scattering efficiency ensures lasting coverage and structural integrity. In printing inks, it delivers precise chromatic accuracy for vivid, durable graphics.
 

 

2. Plastics & Rubber
TiO2 serves as a whitener and performance enhancer in plastics and rubber, improving thermal stability and UV resistance. Key uses involve PVC piping, PE films, UV-shielded tire components, and appliance housings (e.g., refrigerators, washing machines) to maintain whiteness and prevent discoloration.

3. Cosmetics & Personal Care
In cosmetics, TiO2 functions as a mineral UV filter, scattering UVA/UVB radiation for skin protection, while providing whitening and texture refinement. It is prevalent in sunscreens, makeup formulations, whitening toothpaste, and bar soaps for enhanced sensory properties.

 

1. Paper Manufacturing
   TiO2 functions as an additive and surface enhancer in paper production, elevating brightness, surface finish, and print performance. It is critical for premium-grade printing sheets and glossy coating formulations.

2. Ceramics & Glass Industries
   In ceramics, TiO2 integrates into coatings to amplify gloss and abrasion resistance. For glass, it neutralizes iron-induced greenish hues as a color-correcting agent, applied in tile glazes, dishware finishes, and transparent container glass.

 

 

1. Photocatalysis & Environmental Applications
   Leveraging its UV-activated photocatalytic capability, TiO2 breaks down harmful organic compounds. Key uses span air purification (decomposing formaldehyde/VOCs), self-cleaning surfaces (eliminating organic residues), and water treatment (neutralizing toxins and heavy metals).

2. Energy & Electronic Technologies
   In energy systems, TiO2 serves as an electrode material for lithium-ion batteries (e.g., Li4Ti5O12 anodes) and enhances dye-sensitized solar cells (DSSCs) via light absorption layers, boosting energy conversion. Its durability and photo-responsive properties also advance electronic component performance.

8. Food & Pharmaceuticals
Despite regulatory limitations in certain areas, titanium dioxide (E171) was once widely utilized as a white pigment in foods (e.g., confectionery, gum) and pharmaceuticals (e.g., pill coatings, capsules) for coloration and coating. Current applications now mandate rigorous safety adherence.

3. Challenges & Solutions in TiO₂ Pigment Use

Challenges:

1. Photocatalytic breakdown (paint powdering)

2. Agglomeration during dispersion

3. Elevated expense

4. Regulatory restrictions (e.g., EU E171)

Solutions:

1. Apply surface-coated rutile TiO2 (SiO2/Al2O3 coatings).

2. Enhance milling & employ dispersion aids.

3. Combine with fillers (e.g., CaCO3).

4. Adopt non-food-grade or alternative opacifying agents.
