Write me a short paragraph about the difference of anatase and rutile crystal configurations
Anatase and rutile are two crystalline forms of titanium dioxide, a white, opaque mineral used in many industrial and consumer applications. The main difference between anatase and rutile is their crystal structure. Anatase has a tetragonal structure, meaning it has four sides and four angles, while rutile has a more compact, rhombohedral structure with six sides and angles. Anatase is also typically less dense and more reactive than rutile, and it often has a higher surface area, which makes it useful in photocatalytic applications. Rutile, on the other hand, is more stable and has a higher refractive index, which makes it valuable in the production of high-index glass, optical coatings, and other optical applications.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
