✦ Synopsis

The vaporization behavior of boron phosphate has been studied by using Knudsen effusion mass spectrometry. The vapor over BPO 4 consists of B 2 O 3 , P 4 O 10 , PO 2 , BPO 4 (platinum cell) and B 2 O 3 , PO, PO 2 , BPO 3 , BPO 4 (molybdenum cell). Standard enthalpies of formation and atomization (kJ/mol) were derived for BPO 4 (g) (À1000 AE 15 and 2863 AE 16) and for BPO 3 (g) (À731 AE 15 and 2347 AE 16), respectively.
