The vaporization behavior of boron phosphate has been studied by using Knud
sen effusion mass spectrometry. The vapor over BPO4 consists of B2O3, P4O10
, PO2, BPO4 (platinum cell) and B2O3, PO, PO2, BPO3, BPO4 (molybdenum cell)
. Standard enthalpies of formation and atomization (kJ/mol) were derived fo
r BPO4 (g) (-1000 +/- 15 and 2863 +/- 16) and for BPO3 (g) (-731 +/- 15 and
2347 +/- 16), respectively, Copyright (C) 1999 John Whey & Sons, Ltd.
