    Thermodynamic Study of the Vaporization of Cerium Orthophosphate
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (1), 1977) Guido, M; Balducci, G; De Maria, G; Gigli, G
    The high temperature Knudsen cell mass spectrometric technique has been used to study the vaporization behaviour of solid cerium orthophosphate over the temperature range 1700–1850 K. From the second- and third-law analyses of the equilibrium reaction: CePO4(s)= CeO2(g)+ PO2(g), the following standard heat of formation of CePO4(s) has been derived: ΔH°298,f[CePO4(s)]=–1898.5 ± 31.5 kJ mol–1. These results are discussed and compared with those obtained by other authors for other LnPO4 compounds.
