Info

Effect of water ingress • Vibrational spectroscopy allows the chemical speciation to be determined – Raman spectroscopy measures bond polarisation – Infrared measures dipole moments • Observe the formation of HF species in the salt – Associated with KF (extremely hygroscopic and deliquescent)
H 2 O Decomposition in Fluoride <strong>Salt</strong>s • Molecular dynamics using DFT used to study the stability of H 2 O in fluoride salts. • Deviation from stoichiometry found to break H 2 O into OH - and free H + (forming HF in hyper-stoichiometric salt). • Calculations carried out at 1000 K with a time step of 1 fs. (Run for 0.1 ns). • Phenomenon seen in non-stoichiometric F 2 LiNa and F 3 LiNaK. Stoichiometric F 3 LiNaK Non-Stoichiometric F 3 LiNaK
