I try to get data on the structure of beta-cristobalite, SiO2. On I find the following:
Cristobalite Downs R T, Palmer D C American Mineralogist 79 (1994) 9-14 The pressure behavior of alpha cristobalite P = room pressure _database_code_amcsd 0001629 4.9717 4.9717 6.9223 90 90 90 P4_12_12 atom x y z B(1,1) B(2,2) B(3,3) B(1,2) B(1,3) B(2,3) Si .30028 .30028 0 .0077 .0077 .00401 -.0003 .0008 -.0008 O .2392 .1044 .1787 .0244 .0086 .0062 -.0013 .0027 .0005
I have no idea what this means. I know the unit cell should have 4 Si atoms, and each should bond to 4 O atoms. What information is given from these numbers (all of them)?
Yes, the mineral malachite does have a crystal structure.
The crystal structure of phosphorous is monoclinic.
Solid oxygen has a cubic crystalline structure. Solid nitrogen has a hexagonal crystalline structure.
Calcium peroxide has a tetragonal crystalline structure.
The crystal structure of Si2Ti is cubic, with space group Pn-3m (cubic diamond structure). It consists of silicon and titanium atoms arranged in a diamond lattice with each silicon atom bonded to four titanium atoms.
A mineralogist can perform various tests on the mineral, such as hardness, cleavage, color, streak, and specific gravity testing. They can also use specialized equipment like X-ray diffraction or spectroscopy to analyze the mineral's composition and crystal structure. Consulting with other experts or referencing mineralogy resources can also help in identifying the mineral.
There is no crystal structure.
Yes, the mineral malachite does have a crystal structure.
Beryllium's crystal structure is hexagonal.
The crystal structure of phosphorous is monoclinic.
The crystal structure of fermium was not determined.
a crystal structure is a turtle in disguise
The crystal structure of radium is cubic, body-centered.
Yes. Diamond is isometric, graphite is hexagonal.
Crystal structure is for solids and for gases. Helium is a gas and doesn't form any crystal.
a crystal.
The crystal structure of fluorine is a monoclinic structure at normal atmospheric pressure. It forms a lattice of individual F2 molecules arranged in layers.
