What type of unit cell is rutile?
tetragonal unit cell
Rutile has a tetragonal unit cell, with unit cell parameters a = b = 4.584 Å, and c = 2.953 Å. The titanium cations have a coordination number of 6, meaning they are surrounded by an octahedron of 6 oxygen atoms. The oxygen anions have a coordination number of 3, resulting in a trigonal planar coordination.
What unit cell does gold possess?
The crystal structure of gold is face‐centered cubic. Its unit cell, or basic repeating unit, shows that it contains four gold atoms and that the gold atoms touch along the face diagonal.
What is the unit cell of TiO2?
These results provide important characteristics that should be considered during various engineering applications of TiO2 nanofluids. The space group of the titanium oxide is I41/amd. In this structure, the titanium oxide has four titanium and eight oxygen atoms in a unit cell [15] .
Is rutile cubic?
Rutile is an example of a non-cubic close packed structure.
What is gold rutile?
Gold Rutilated Quartz is a beautiful energy-filled stone with an array of patterns. Each pattern is different and incredibly powerful. Rutile has one of the highest physical properties as it serves as a refractive index that allows more light to disperse than any other mineral.
What are the properties of rutile?
Rutile is oxide group mineral with formula: titanium dioxide (TiO2)….Rutile Physical Properties.

What is the volume of a gold atom?
Since one mole of gold contains Avogadro’s number of atoms, we can therefore calculate the volume of 1 atom as 7.55 cm3 ÷ 6.02 × 1023 = 1.25 × 10–23 cm3.
Is gold metal a simple cubic unit cell?
Metallic gold has a face-centered cubic unit cell (part (c) in Figure 12.5). How many Au atoms are in each unit cell? Strategy: Using Figure 12.5, identify the positions of the Au atoms in a face-centered cubic unit cell and then determine how much each Au atom contributes to the unit cell.
What is the formula of rutile?
Rutile is a titanium oxide of formula TiO2. It is a member of the oxides and hydroxides group.
What is golden rutile made of?
Rutile is composed of titanium dioxide which is a main component of refractory ceramics, titanium metal, and the bright white pigment used in plastics and other items that are bright white in color. Interestingly enough, it is also used in sunscreen due to its ability to absorb ultraviolet (UV) light.
What is the unit cell of rutile?
The unit cell of rutile. Ti atoms are gray; O atoms are red. Rutile has a tetragonal unit cell, with unit cell parameters a = b = 4.584 Å, and c = 2.953 Å. The titanium cations have a coordination number of 6, meaning they are surrounded by an octahedron of 6 oxygen atoms.
What is the composition of rutile?
Natural rutile may contain up to 10% iron and significant amounts of niobium and tantalum . Rutile derives its name from the Latin rutilus (‘red’), in reference to the deep red color observed in some specimens when viewed by transmitted light.
Why is rutile used in optical materials?
Owing to these properties, it is useful for the manufacture of certain optical elements, especially polarization optics, for longer visible and infrared wavelengths up to about 4.5 micrometres. Natural rutile may contain up to 10% iron and significant amounts of niobium and tantalum .
What is the unit cell of titi?
Ti atoms are gray; O atoms are red. Rutile has a tetragonal unit cell, with unit cell parameters a = b = 4.584 Å, and c = 2.953 Å. The titanium cations have a coordination number of 6, meaning they are surrounded by an octahedron of 6 oxygen atoms.
