Calcium Fluoride Crystal

Calcium fluoride - Wikipedia

The compound crystallizes in a cubic motif called the fluorite structure. Ca centres are eight-coordinate, being centered in a cube of eight F centres. Each F centre is coordinated to four Ca centres in the shape of a tetrahedron. Although perfectly packed crystalline samples are colorless, the mineral is often deeply colored due to the presence of F-centers. The same crystal structure is found in numerous ionic compounds with formula AB2, such as CeO2, cubic ZrO2, UO2

Fluorite - Wikipedia

Fluorite crystallizes in a cubic motif. Crystal twinning is common and adds complexity to the observed crystal habits. Fluorite has four perfect cleavage planes that help produce octahedral fragments. The structural motif adopted by fluorite is so common that the motif is called the fluorite structure. Element substitution for the calcium cation often includes certain rare earth elements(REE), such as yttrium and cerium. Iron, sodium, and barium are also common impurities. Some fluoride anions may be replaced b…
