The standard molar enthalpies of solution of cerium and lanthanum silicates (b-Ce2Si2O7 and b-La2Si2O7) in (6.20 mol•dm -3 HCl + 0.147 mol•dm -3 HF) (aq) were measured. From these values the standard molar enthalpies of formation have been deduced: DfH°m(Ce2Si2O7, cr, b, 298.15 K) = -(3807.6 2 4.5)
A potassium zirconium pyrogermanate, K 2 ZrGe 2 O 7 , was synthesized hydrothermally at 1803C from a mixture of zirconium propionate, GeO 2 , and KOH. The crystal structure was solved from in-house X-ray powder data by direct methods and Fourier analysis. Re5nement of the structure was e4ected by th
