Product Description

Product Overview

Titanium dioxide (TiO2), also known as titanium(IV) oxide or titania, is a widely used inorganic compound with numerous applications. It's a white pigment used in paints, coatings, plastics, paper, and other materials. 

 

Key Characteristics

Property	Description
Chemical Formula	TiO2
Molecular Weight	79.866 g/mol
Crystal Structures
- Rutile	High density, refractive index (2.7), excellent stability. Used in high-performance coatings and plastics.
- Anatase	High photocatalytic activity, lower refractive index (2.5). Used in photocatalysts and self-cleaning materials.
- Brookite	Rare, limited industrial applications.
Physical Properties
- Color	White powder (pure form), slight color variations based on crystal structure.
- Density	Rutile: 4.23 g/cm³; Anatase: 3.89 g/cm³.
- Melting Point	~1843°C (decomposes).
- Solubility	Insoluble in water, dilute acids, and organic solvents. Soluble in concentrated sulfuric acid and hydrofluoric acid.
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
Titanium dioxide (TiO₂) is widely used in coatings and inks for its opacity, weather resistance, and anti-chalking properties. For example, in architectural coatings (e.g., latex paint), automotive paints, and marine coatings, its high refractive index provides excellent coverage and durability. It is also essential in printing inks for high color fidelity.
 

2. Plastics & Rubber
As a whitening agent and reinforcing additive, TiO₂ enhances the heat resistance and UV stability of plastics and rubber products. Common applications include PVC pipes, PE packaging films, tire sidewalls (to prevent UV degradation), and white appliance casings (e.g., refrigerators, washing machines) for whitening and anti-yellowing.

3. Cosmetics & Personal Care
In cosmetics, TiO₂ acts as a physical UV blocker, reflecting UVA/UVB rays to protect the skin, while also serving as a whitening agent and texture enhancer. It is commonly found in sunscreens, foundations, toothpaste (whitening), and soaps (improving texture).
 

4. Paper Industry
TiO₂ is used as a filler and coating agent in paper manufacturing to improve whiteness, smoothness, and printability. It is particularly important in high-quality printing paper and glossy paper coatings.

5. Ceramics & Glass
In ceramics, TiO₂ is added to glazes to enhance gloss and wear resistance, while in glass production, it acts as a decolorizer to neutralize the green tint caused by iron impurities. Typical applications include ceramic tiles, tableware, and glass containers.
 

6. Photocatalysis & Environmental Protection
Due to its photocatalytic properties, TiO₂ can degrade organic pollutants under UV light. Applications include air purification (breaking down formaldehyde and VOCs), self-cleaning glass (decomposing surface stains), and wastewater treatment (removing organic toxins and heavy metals).

7. New Energy & Electronics
In the energy sector, TiO₂ is used as an electrode coating material in lithium-ion batteries (e.g., lithium titanate anodes) and as a light-absorbing layer in dye-sensitized solar cells (DSSCs) to improve efficiency. Its chemical stability and photoactivity make it valuable in electronic devices.

8. Food & Pharmaceuticals
Despite regulatory restrictions in some regions, TiO₂ (food additive E171) was historically used as a whitening agent in food (e.g., candies, chewing gum) and as a coating/coloring agent in pharmaceuticals (e.g., tablet coatings, capsules). Its use now requires strict safety compliance.  

Titanium Dioxide (TiO₂) as a Pigment: Comprehensive Technical Data

1. Performance Comparison vs. Other White Pigments

Pigment	Refractive Index	Opacity	UV Resistance	Cost	Main Limitations
TiO2 (Rutile)	2.7	5star	5star	High	Cost, potential photocatalysis
Zinc Oxide (ZnO)	2.0	2star	4star	Medium	Poor opacity, reactivity
Lithopone (ZnS + BaSO4)	1.8	2star	2star	Low	Poor durability
Calcium Carbonate (CaCO3)	1.6	1star	1star	Very Low	Filler only, no opacity

 

2. Major Industrial Applications

Industry	Function of TiO	Example Products
Paints & Coatings	- Primary opacifier - UV protector	Wall paints, car finishes, powder coatings
Plastics	- Whitening agent - UV stabilizer	PVC windows, food packaging, toys
Inks	- Brightness enhancer - Opacity provider	Offset inks, packaging inks
Paper	- Coating pigment - Brightness booster	High-gloss magazine paper

 
 

3. Challenges & Solutions in TiO₂ Pigment Use

Challenge:
1.Photocatalytic Degradation (chalking in paints)
2.Dispersion Issues (agglomeration)
3.High Cost
4.Environmental Regulations (e.g., EU E171 ban)

Solution:
1.Use surface-treated rutile TiO2 (SiO2/Al2O3 coated).
2.Optimize grinding & use dispersing agents.
3.Blend with extenders (e.g., CaCO3) where possible.
4.Switch to non-food-grade or alternative opacifiers.
