Oct 30, 2004 the bonding between ca and f atoms is predominantly ionic with a midbond density slightly higher due to interactions between neighboring charges and also to the resolution of the mem technique. similar studies on antifluorite structures will complement the understanding of bonding and electrostatic interactions in these compounds.
Fluorite caf 2, an important nonrenewable mineral that is primarily used for the manufacture of hydrofluoric acid, glass, cement, fillers, and as a flux regent in steel making, has in recent years been considered an important strategic mineral 1,2,3,4 natural ore deposits, fluorite is mostly associated with other calciumbearing minerals, such as calcite and scheelite.

Fluorite or fluorspar is a mineral composed of calcium fluoride caf2, the principal fluorinebearing mineral. it occurs as cubic, isometric crystals and cleavable masses. when pure, it is colorless and transparent, or translucent with a glassy luster. impurities cause color in the stone, and several varieties exhibit fluorescence.

Fluorite has an extensive range of colours such as blue, green, pink, purple, and yellow. it is an attractive and striking stone because habitually more than one shade takes place in such a single stone. in fact, the earliest egyptians use this stone to shape out statues and scarabs, which most chinese has utilized it for carvings more than 300
Density functional theory simulations, including a correction for dispersive interactions, were performed to investigate the adsorption of water on the main cleavage plane of the fluorite, namely, the 111 surface. in the case of a single molecule of water, we observe that the molecular form is preferred over the dissociated one, and absorbs on the surface with an energy of 55 kj mol1
Fluorite thermoluminescence spectra commonly contain abundant rare earth lines. color wyrouboff 1366 was an early advocate of the organic coloring theory. blount and sequeira 1919 and garnett 1920 demonstrated the presence of hydrocarbons in fluorite. recently vlorrison 1935 has attributed
