Fluorite (CaF 2), mainly composed of calcium fluoride, has a cubic crystal structure with a space group of Fm-3 m, having a = b = c = 0.5463 nm and α = β = γ = 90° [10], as shown in Fig. 3.The calcium atoms are eightfold coordinated to eight surrounding fluorine atoms at a distance of 0.237 nm. Conversely, the fluorine atoms are surrounded …
Abstract. Samples from 13 beaches along the northern Spanish coast, a region with a history of heavy industries, were first screened to identify signs of pollution.
