WebCalcium fluoride (CaF2) is an insoluble ionic compound composed of Ca 2+ and F − ions. It occurs naturally as the mineral “Fluorite” (also called fluorspar) and as “Blue-John”. This salt is the source of most of the world’s fluorine. This insoluble solid adopts a cubic structure wherein calcium is coordinated to eight fluoride ... WebMay 23, 2012 · 1. The calcium cation is much bigger in size compared to the fluorine anion, hence has less polarising power. The polarisation effects are way much less due to the additional small size (relative) of the fluorine anion (low polarisability). This leads me to conclude that calcium fluoride is highly ionic in nature, and should be soluble in water.
