“…In Eu, Gd) at 515-1570 K (Popa et al 2007a), as well as for PuPO 4 (Thiriet et al 2005b) and (Pu 0.1 La 0.9 )PO 4 (Popa et al 2007b) at 5-300 K. Entropies, calculated from heat capacity (Thiriet et al 2005c), together with measured enthalpies of formation for the LnPO 4 series, as reported by Ushakov et al (2001), provide the Gibbs free energies of these phases.…”

“…There are no experimental data on Am or Cm phosphates, and therefore we only can compare our data to a Pu‐bearing monazite analyzed by Popa et al . with a value of ∼110 J·(mol·K) −1 and the value published earlier by Thiriet et al . for PuPO 4 of 114.5 J·(mol·K) −1 at ambient temperature.…”

Synthetic La1−xEuxPO4 monazite‐type ceramics with 0 ≤ x ≤ 1 have been characterized by ultrasound techniques, dilatometry, and micro‐calorimetry. The coefficients of thermal expansion and the elastic properties are, to a good approximation, linearly dependent on the europium concentration. Elastic stiffness coefficients range from 182(1) to 202(1) GPa for c11 and from 53.8(7) to 61.1(4) GPa for c44. They are strongly dependent on the density of the sample. The coefficient of thermal expansion at 673 K is 8.4(3) × 10−6 K−1 for LaPO4 and 9.9(3) × 10−6 K−1 for EuPO4, respectively. The heat capacities at ambient temperature are between 101.6(8) J·(mol·K)−1 for LaPO4 and 110.1(8) J·(mol·K)−1 for EuPO4. The difference between the heat capacity of LaPO4 and the Eu‐containing solid solutions is dominated by electronic transitions of the 4f‐electrons at temperatures above 75 K.

“…The first synthesis of PuPO 4 was reported by Bjorklund [14] and the compound was further characterised in references [15][16][17]. Its stability domain under vacuum was established to be between 1273 K (below this limit the compound exists in equilibrium with PuP 2 O 7 ) and 1673 K, temperature at which it starts to decompose in air to PuO 2 [14].…”
