Suppliers play a crucial role in transforming these raw materials into usable titanium dioxide. They employ specialized extraction techniques such as the Becher process for ilmenite or the sulfate process for rutile and anatase, which involve chemically treating the ore to produce titanium dioxide. In the sulfate process, for example, the ore is treated with sulfuric acid to form titanyl sulfate, which is then calcined to yield titanium dioxide.

TiO2 comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO2, including the concern for genotoxicity, used forms of TiO2 that are not considered acceptable for use in food and have different properties than food-grade TiO2. Other studies did use food-grade TiO2, but took steps to break the material down into smaller particles than what would normally be found in food.

Titanium dioxide exists primarily in three crystalline forms rutile, anatase, and brookite. Among these, anatase is characterized by its unique electronic properties and higher photocatalytic activity, making it suitable for applications requiring enhanced light absorption and reactivity. Its ability to act as a photocatalyst enables the breakdown of organic pollutants, making it a valuable component in environmental remediation strategies.

One of the most significant impacts of TIO2 in factories is its role in photocatalysis. This process involves the acceleration of photoreaction in the presence of light and a catalyst—in this case, TIO2. By harnessing the power of sunlight or artificial UV light, TIO2 can break down organic pollutants into substances, playing a crucial role in environmental remediation efforts within industrial settings. This not only helps factories minimize their environmental footprint but also reduces the costs associated with waste treatment and disposal.
