Understanding TiO2 Types and Key Manufacturers

Titanium dioxide (TiO2) is a widely used compound in various industries, known for its brilliant white color and excellent opacity. It serves as a key ingredient in products ranging from paints and coatings to plastics, food, and cosmetics. The significance of TiO2 has made it a crucial material in manufacturing processes, leading to the development of various types based on their properties and intended applications.

Types of Titanium Dioxide

1. Anatase This form of TiO2 is characterized by its tetragonal crystal structure. Anatase TiO2 is primarily used in photocatalytic applications, including water treatment, air purification, and self-cleaning surfaces. Its high photocatalytic activity makes it ideal for these applications, as it can effectively break down organic pollutants under UV light.

2. Rutile Rutile TiO2 is the more stable form of titanium dioxide and has a higher refractive index compared to its anatase counterpart. This property makes rutile ideal for use in the pigment industry, particularly in paints, coatings, and plastics. Its excellent covering power and durability ensure that products maintain their color and finish over time.

3. Brookite The least common form of TiO2, brookite, possesses unique properties that make it suitable for specific niche applications. While not as widely used as anatase or rutile, brookite can be advantageous in certain photocatalytic processes and in the development of new composite materials.

Manufacturers of TiO2 focus on optimizing the characteristics of these types to meet the diverse needs of various industries. The production process for TiO2 typically involves either the sulfate process or the chloride process, each yielding different qualities and purities of the final product.
