The Crystal Chemistry of Ca 10-y (SiO 4 ) 3 (SO 4 ) 3 Cl 2-x-2y F x Ellestadite
Fluor-chlorellestadite solid solutions Ca10(SiO4)3(SO4)3Cl2-xFx, serving as prototype crystalline matrices for the fixation of hazardous fly ash, were synthesized and characterized by powder X-ray and neutron diffraction (PXRD and PND), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FTIR). The lattice parameters of the ellestadites vary linearly with composition and show the expected shrinkage of unit cell volume as fluorine (IR = 1.33 Å) displaces chlorine...[Show more]
