Titanium dioxide TiO2 is a naturally occurring mineral that exists in various crystal structures including rutile. anatase. and plagioclase. Rutile is the most commonly found form. characterized by a square cell structure where titanium atoms occupy octahedral sites and oxygen atoms occupy tetrahedral sites. This particular structure is known for its stability and density. with the cation being surrounded by six oxygen anions. Similarly. anatase also has a tetrahedral structure. but the arrangement of titanium and oxygen atoms differs. In this case. the titanium atoms are octahedrally coordinated to oxygen but share sides rather than edges. resulting in a lower structural density compared to rutile. On the other hand. platelet titanite is the least common form of TiO2 with a rhombohedral crystal system and unique arrangements of titanium and oxygen units. Here. the titanium cations are also octahedrally coordinated to oxygen anions but share some edges with other octahedra on the rim. ...

Various analytical techniques can be used to assess the quantity and quality of titanium dioxide. such as X-ray fluorescence XRF. inductively coupled plasma atomic emission spectroscopy ICP-AES. scanning electron microscopy SEM. X-ray diffraction XRD. UV-Vis spectroscopy. Fourier transform infrared spectroscopy FTIR. BET surface area analysis. and inductively coupled plasma mass spectrometry ICP-MS. These methods offer non-destructive means to determine the composition and properties of materials. whether through identifying spectral lines emitted from a sample or analyzing particle shape and structure. Depending on the type and state of the sample. as well as the desired information. techniques may include acid digestion. grinding. and sieving for optimal results.
