Abstract
emical (EPM data), TG–DSC studies and structural investigations indicate that mosandrite presents a particular chemical composition (low Ca, Na and F contents, high amount of H2O), unit-cell parameters (a 7.398, b 5.595, c 18.662 Å, b 101.37°, V 757.29 Å3; space-group symmetry P21/c; Z = 2), and a rinkite-type structure characterized by a low occupancy of the M(2) and M(3) sites.File in questo prodotto:
