Fluorite structure Wikipedia

Many compounds, notably the common mineral fluorite (CaF 2), adopt this structure. Magnesium compounds such as Mg 2 X, where X can be one of the elements Si, Ge, Sn, or Pb, are said to have an antifluorite structure because the locations of the anions and cations are reversed relative to fluorite (an anti-structure ); the anions occupy the FCC regular sites whereas the cations occupy the

Synthesis and crystal structure of fluorite-type

Abstract In this study, we synthesized the solid solution system between La2Zr2O7 and La3TaO7 with a fluorite-type structure for the first time by the polymerized complex method and refined its crystal structural parameter using the Rietveld method. Furthermore, we synthesized a garnet-type Li-ion conductor by the precursor method which used a solid solution, La2+xZr2-2xTaxO7 (x = 0.4), as a

The most common way to describe a crystal structure is to refer to the size and shape of the material's characteristic unit cell, which is the simplest repeating unit within the crystal. In principle, one can reconstruct the structure of an entire crystal by repeating the unit cell so as to create a three-dimensional lattice.
