When it comes to titanium dioxide, there are three distinct varieties: Anatase, Rutile, and Brookite. Each type of titanium dioxide has its own unique characteristics, making it suitable for different types of applications. In this blog, we’ll take a closer look at the differences between Anatase, Rutile and Brookite, and explore how each type is used.
Characteristics of anatase, rutile and brookite
Anatase, rutile, and brookite are three distinct minerals that have unique characteristics that set them apart. Anatase is a titanium dioxide mineral that is usually found in shades of white, yellow, and brown. It is known for its highly reflective properties, making it desirable in the production of paints and pigments.

Brookite is a rare, reddish-brown oxide mineral. It has been used as an abrasive and in the production of jewelry and ceramics. The main difference between these three minerals is their chemical composition, visual appearance, and practical applications.

How anatase, rutile and brookite differ
Anatase, rutile and brookite are three different forms of titanium dioxide, a mineral composed of oxygen and titanium. Anatase and rutile are the two most common forms of titanium dioxide, while brookite is much rarer.
Anatase has a tetragonal structure, meaning its crystals form in four directions. Rutile has a tetragonal structure as well, but its crystals are typically longer, creating a cylindrical shape.
In contrast, brookite has an orthorhombic structure, with crystals forming in six directions. This difference in structure affects how the mineral absorbs and reflects light, as well as its thermal and electrical conductivity. Anatase and rutile are the more common forms of titanium dioxide, making them more widely available for use in products like cosmetics and sunscreen.

Applications of anatase, rutile and brookite
Anatase, rutile and brookite are three different crystal structures of titanium dioxide, a mineral commonly used in a variety of applications. Anatase has a tetragonal structure, with a low refractive index, making it ideal for use in sunscreen and cosmetics. Rutile, by contrast, has a higher refractive index and is more commonly used for optical applications such as lenses and prisms.
Rutile, by contrast, has a higher refractive index and is more commonly used for optical applications such as lenses and prisms. Finally, brookite has an orthorhombic structure and is primarily used for its electrical properties, including as a dielectric material or for fuel cells. All three forms of titanium dioxide have distinct properties that make them suitable for different types of applications.
Advantages and disadvantages of anatase, rutile and brookite
When it comes to differentiating between anatase, rutile and brookite, it’s important to understand the advantages and disadvantages of each type of mineral. Anatase is a mineral form of titanium dioxide, which is commonly used in the production of paints, plastics, and paper.
It is known for its superior optical properties and chemical stability. Rutile is also a form of titanium dioxide, and is the most common mineral form of this element. It is typically used in applications such as welding rods, electrodes, and refractory materials.
Brookite is an iron titanium oxide and is often used in ceramic glazes and enamels. It is also known for its superior thermal properties.
Cost comparison of anatase, rutile and brookite
The three most common forms of titanium dioxide are anatase, rutile, and brookite. Each of these forms has different physical and chemical properties, making them suitable for different applications.
Rutile is the most abundant form and is most commonly used for paint and coatings. Brookite is the least stable form and is generally used for specialty applications, such as photocatalysis.
All three forms of titanium dioxide are relatively low-cost, however, anatase is the most expensive due to its scarcity. Rutile is the most cost-effective form, while brookite is usually the cheapest.
Bottom Line
In conclusion, anatase, rutile, and brookite are all forms of titanium dioxide, but they have distinct differences. Anatase has a tetragonal crystal structure, while rutile has a tetragonal-dipyramidal structure and brookite has an orthorhombic structure.
Anatase is the least stable of the three, and has the highest surface area and highest reactivity. Rutile is the most common form of titanium dioxide and has the highest melting point and refractive index. Brookite is the most thermodynamically stable form of titanium dioxide, and has the highest hardness and lowest band gap.
All three forms of titanium dioxide are widely used in a variety of industrial applications.
