What is titanium dioxide?
Titanium dioxide (TiO2) is a white, odorless, and insoluble powder that is widely used as a white pigment in various industries such as paint, plastic, paper, and cosmetic products. It is also used in sunscreens to provide protection against ultraviolet (UV) rays. TiO2 Titanium dioxide is a thermally stable and chemically inert compound, which makes it suitable for use in various applications. In addition, it has a high refractive index, making it useful in optical applications.
Titanium dioxide chemical formula
The chemical formula for Titanium dioxide is TiO2.
Titanium dioxide chemical structure
Titanium dioxide has a crystal structure known as the rutile form, which consists of a repeating pattern of Titanium and oxygen atoms. The chemical structure of TiO2 can be represented as follows:
Ti - O - Ti - O - ...
Where Ti represents a Titanium atom and O represents an oxygen atom.
Chemical Properties of titanium dioxide
- Insoluble in water and organic solvents
- High refractive index
- Chemically inert and thermally stable
- Good electrical insulator
- Poor conductor of heat
- Photocatalytic (can activate chemical reactions upon exposure to UV light).
Physics Properties of Titanium Dioxide
- High refractive index
- Low absorption of visible light
- Wide bandgap energy (about 3 eV)
- Strong light scattering capability
- High thermal stability
- Poor electrical conductivity.
Titanium Dioxide uses
Titanium dioxide (TiO2) has various applications including:
- Pigment in paint, plastic, and paper.
- Sunscreen active ingredient
- Food colorant and opacifier
- Catalysts in chemical reactions
- Water purification
- Ceramic and glass production
- Photocatalyst in air purification and self-cleaning surfaces.
Titanium dioxide in food
Titanium dioxide (TiO2) is used as a food colorant and opacifier in various food products, including:
- Confectionery (e.g. candies, chewing gum)
- Dairy products (e.g. ice cream, yogurt)
- Baked goods (e.g. pastries, cakes)
- Sauces and condiments
- Beverages (e.g. sports drinks)
- Pharmaceuticals (e.g. tablets, capsules)
- Personal care products (e.g. toothpaste)
Titanium Dioxide side effects
Titanium dioxide is a widely used substance in various industries, including cosmetics, food, and pharmaceuticals. However, long-term exposure to high levels of Titanium dioxide dust may cause lung problems such as pneumoconiosis. Ingestion of large amounts can lead to gastrointestinal issues like abdominal pain and diarrhea. Some studies suggest that titanium dioxide may be a carcinogen when inhaled in high doses, but more research is needed to confirm this. Overall, the safety of Titanium dioxide depends on various factors, including the amount and frequency of exposure, as well as the form and size of the particles.
Titanium Dioxide price
The price of Titanium dioxide varies and is influenced by several factors, such as supply and demand, production costs, and geographical location. As of 2021, the average price for titanium dioxide was around $2,000 to $3,000 per metric ton. The price can fluctuate based on market conditions and trends, such as changes in demand from various industries, fluctuations in the cost of raw materials, and geopolitical events. To get the most current and accurate information on the price of Titanium dioxide, it is recommended to check with reliable industry sources and consult with market analysts.
