Titanium Dioxide An Overview of Anatase-Type TiO2 Suppliers

Titanium dioxide (TiO2) is one of the most significant compounds used in various industries, such as paints, coatings, plastics, and even food products, due to its high refractive index and UV resistance. Among the three forms of titanium dioxide rutile, anatase, and brookite, anatase-type TiO2 has gained particular attention for its unique properties and applications. This article delves into the characteristics of anatase TiO2 and highlights key suppliers in the market.

Understanding Anatase-Type TiO2

Anatase TiO2 is one of the two most stable allotropes, alongside rutile. It exhibits a tetragonally symmetrical crystal structure, which imparts distinct optical and photocatalytic properties that are highly desirable in various applications. Generally, anatase is known for its superior photocatalytic activity compared to rutile, making it particularly favored in environmental remediation and energy applications, such as photocatalytic water splitting and air purification.

In terms of particle size, anatase TiO2 can be engineered to nanoscale, which amplifies its surface area and enhances its interaction with light. This property is crucial for the efficacy in photodegradation processes, where contaminants in wastewater can be broken down by light exposure. Moreover, anatase TiO2 has been increasingly incorporated into solar cells, enhancing their efficiency owing to its ability to absorb UV light.
