Understanding the Types and Suppliers of Titanium Dioxide

Titanium dioxide (TiO2) has emerged as one of the most significant materials used across a broad range of industries, thanks to its remarkable pigmenting, ultraviolet light absorbing, and photocatalytic properties. With its application spanning from paint and coatings to plastics, paper, pharmaceutical, and cosmetics, understanding the types of titanium dioxide and how to source them is crucial for manufacturers and industrial users.

Types of Titanium Dioxide

Titanium dioxide can primarily be classified into two types based on its crystalline structure anatase and rutile.

1. Anatase This form is generally preferred in applications requiring high UV absorption and photocatalytic activity, such as in self-cleaning surfaces, sunscreens, and cosmetics. Anatase titanium dioxide has a lower density and is less opaque than rutile, making it suitable for mastics and certain coatings where transparency is desirable.

2. Rutile Rutile titanium dioxide boasts superior whiteness, opacity, and durability, making it the preferred choice in the paint and coatings industry. Rutile is also more stable under heat and offers better resistance to discoloration due to environmental factors, thus it is extensively used in exterior applications and industrial coatings.

In addition to these primary types, titanium dioxide pigments can also come in different forms based on the treatment they undergo. These treatments can enhance their dispersibility, gloss, and durability. Some significant variations include

- Surface-treated TiO2 This involves applying a coating (often of silica, alumina, or other compounds) to the titanium dioxide particles to improve their performance in specific applications. - Nano-Titanium Dioxide The emergence of nanotechnology has led to the creation of nano-sized titanium dioxide particles. These find applications in advanced technologies like photocatalysis, water treatment, and high-performance coatings.
