The enthalpy increments of Y Si O and Dy Si O have been measured by drop-calorimetry 2 2 7 2 2 7 ลฝ . ลฝ . from T s 516.7 to 928.4 K, and T s 516.7 to 918.2 K, respectively. The standard molar enthalpy of formation of monoclinic Y Si O has been deduced from its enthalpy of solution 2 2 7 . y3 . y3 T ลฝ
The standard molar enthalpies of solution of cerium and lanthanum silicates (b-Ce2Si2O7 and b-La2Si2O7) in (6.20 molโขdm -3 HCl + 0.147 molโขdm -3 HF) (aq) were measured. From these values the standard molar enthalpies of formation have been deduced: DfHยฐm(Ce2Si2O7, cr, b, 298.15 K) = -(3807.6 2 4.5)
