Micron-size meteoritic particles were flash heated to temperatures as high as Planetary atmospheres 2900 K in a Meteor Ablation Simulator (MASI), and the ablation of PO and Ca recorded simultaneously by laser Ablation induced fluorescence. Apatite grains were also ablated as a reference. The speciation of P in anhydrous chondritic Phosphorus thermodynamics porous Interplanetary Dust Particles was made by K-edge X-ray absorption near edge structure (XANES) spec- Zodiacal cloud troscopy, demonstrating that P mainly occurs in phosphate-like domains. A thermodynamic model of P in a sil- icate melt was then developed for inclusion in the Leeds Chemical Ablation Model (CABMOD).
