The crystal structure of rutile (TiOz) has been studied at high temperatures up to about 1600° C based on sets of single crystal X-ray diffraction intensities collected on a four-circle diffractometer. The thermal expansion coefficients for the a-and c-axes in the measured temperature range ...
Figure 2 illustrates several structure types in polyhedral representation. The chain nature of the structure of rutile (TiO2) is clearly seen in Figure 2, a. In this structure, the Ti-centered octahedrons linked by sharing edges form chains parallel to the c-edge of the unit cell. This struc...
With increasing the annealing temperature, thecrystal structurechanges from anatase to rutile and the crystallite size increases. Thecrystal structureand some defects such as tilt boundary and dislocation of lanthanum chromates were investigated by high resolution microscopy (HERM). ...
This compound adopts a rutile-type structure with random cat ion distribution on one crystallographic site. The substitution of 50 vanadium by rhenium stabilizes the high temperature form of VO2at room temperature. The cation ratio of 1 : 1 was confirmed by EDX analysis performed by electron ...
Oxides such as TiO2 attain the crystal structure known as rutile. Here the coordination number of cations and anions are different. For example in the case of TiO2, the titanium cations will have a coordination number of six whereas the coordination number of oxygen anions will be three....
It occurs as strong intergrowths of small crystals, colorless to pale yellow, associated with sanidine, mica, magnetite, rutile, titanite, and other Th-U-REE bearing minerals, in miarolitic cavities of a syenitic ejectum. Piergorite-(Ce) is biaxial negative, nα = 1.717 (1), nβ = ...
The generation of plausible crystal structures is often the first step in predicting the structure and properties of a material from its chemical composition. However, most current methods for crystal structure prediction are computationally expensive, slowing the pace of innovation. Seeding structure pred...
The chain nature of the structure of rutile (TiO2) is clearly seen in Figure 2, a. In this structure, the Ti-centered octahedrons linked by sharing edges form chains parallel to the c-edge of the unit cell. This structure type is exhibited by many binary compounds, for example, MnO2, ...
Table 1. Details of crystal data and structure refinement of single crystals. MBI-phosphite and MBI-phosphate-1 were investigated by means of powder XRD as well. XRD measurement of MBI-phosphite powder was carried out on the powder X-ray diffractometer D2 PHASER (Bruker AXS, Germany) in th...
