Titanium dioksida berlaku secara semula jadi di dalam tanah Bumi. Anatase is one of the three mineral forms of titanium dioxide (TiO 2), the other two being brookite and rutile.At higher temperatures, about 915 degrees Celsius, anatase will automatically revert to the rutile structure. Available here In addition, finely powdered rutile is important in producing paints, plastics, and paper. One of the discovered minerals is titanium dioxide. Otherwise, it is colorless or white. Cite Rutile mainly occurs in igneous rocks and metamorphic rocks that are in high temperatures and high-pressure conditions. • Categorized under Chemistry | Differences Between Rutile and Anatase Titanium Dioxide. Anatase Titanium Dioxide is colorless, whereas Rutile Titanium Dioxide is usually found in dark red appearance. It was found that the anatase/rutile TiO 2 heterojunctions exhibited better photocatalytic or PEC activities than the pure rutile or anatase TiO 2, which is due to the matched band levels for built-in electric fields, resulting in efficient separation of photogenerated carriers [ 9, 10, 20 ]. The powdered form of rutile serves as white pigmentation for paints, paper, plastics, foods and other objects which need a white color. Gems come with greater value if there is rutile among them because rutile can make an optical phenomenon known as asterism. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } Rutile and anatase are both used in the white pigmentation of paints, paper, and ceramics. That is because the finely powdered rutile has a brilliant white color. The difference between rutile and anatase titanium dioxide is that rutile titanium dioxide has a deep red color appearance whereas the appearance of anatase titanium dioxide is colorless or white. Both anatase and rutile are tetragonal in structure, but the anatase has octahedrons that share four edges forming the four-fold axis. Exploring Rutile (110) and Anatase (101) TiO2 Water Interfaces by Reactive Force-Field Simulations. Would you please mind changing the second conclusion stating about their colour.

In Rutile, the structure is based on octahedrons of titanium oxide which share two edges of the octahedron with other octahedrons and form chains. Anatase is a metastable mineral form of titanium dioxide (TiO2). According to statistics, it is also one of the top 50 chemicals being produced worldwide. Since both are white pigment so they are white in colour just the simple thing is that anatase is much more whiter than rutile due to its high reflectance of low wavelength light of visible zone. Rutile titanium dioxide is the most common form. It is also hard and has chemical resistant properties.
