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)
