Titanium Dioxide (CAS No. 13463-67-7) Understanding Its Applications and Sources

Titanium dioxide, commonly referred to as TiO2, is a widely used compound in various industries due to its exceptional properties. It is primarily noted for its brightness, high refractive index, and excellent UV resistance, making it an essential ingredient in numerous applications. The chemical is identified by its CAS number 13463-67-7, which serves as a unique identifier in scientific and industrial contexts. This article delves into the applications of titanium dioxide and discusses potential suppliers in the market.

Properties of Titanium Dioxide

Titanium dioxide is a white powder that exhibits both opacity and brightness, making it highly sought after in the production of white pigments. It is also non-toxic and environmentally friendly, which enhances its appeal across various applications. The compound exists in several crystalline forms, with rutile and anatase being the most common.

The efficacy of titanium dioxide as a pigment is attributed to its high refractive index, which allows it to scatter light effectively. This attribute is particularly valued in the paint and coatings industry, where it is used to create bright and durable finish products. Additionally, titanium dioxide has a strong resistance to discoloration and UV degradation, ensuring that products maintain their appearance over time.

Applications of Titanium Dioxide

1. Paints and Coatings The largest application of titanium dioxide is in the paints and coatings sector. Its ability to enhance opacity and brightness makes it an ideal choice for high-quality paints. It is commonly used in both interior and exterior applications, providing durability and protection against environmental factors.

2. Plastics In the plastics industry, titanium dioxide serves as a pigment to improve the whiteness and brightness of materials. It is widely used in the production of plastic products, where it helps in creating visually appealing items while also providing UV protection.

3. Cosmetics Titanium dioxide is used in cosmetics and personal care products due to its ability to provide coverage and enhance the appearance of skin. Its non-toxic nature makes it a preferred choice in formulations like sunscreens, where it acts as a physical sunscreen agent that reflects UV radiation.

4. Food Industry In the food sector, titanium dioxide is occasionally used as a food additive E171, serving as a coloring agent. However, its use in food products has come under scrutiny in recent years, with ongoing research into its safety and potential health impacts.

5. Photocatalysis Beyond its role as a pigment, titanium dioxide is also employed in photocatalytic applications. When exposed to UV light, it can facilitate chemical reactions, making it useful for air purification and self-cleaning surfaces.
